To fulfill the requirements, create classes in C++ for Franchise and League, extend with Player, Batsman, and Bowler classes, utilize polymorphism for desired output, and use file I/O for storing details.
In part a), we create the Franchise and League classes. The Franchise class will have a data member "name" of type string, and the League class will be composed of the Franchise class. Constructors and member functions will be implemented for both classes to handle their respective functionalities.
Moving on to part b), we extend the previous implementation to include the Player, Batsman, and Bowler classes. The Player class serves as the foundation, and the Batsman and Bowler classes are derived from it. Additional data members "country" of type string are added to the Batsman and Bowler classes.
To calculate batting and bowling averages, member functions such as "displayinfo()" will be implemented, which will utilize the given formulas: Batting Average = Runs Scored / Total Innings and Bowling Average = Total number of runs conceded / Total Overs.
Lastly, in part c), file I/O will be used to store the details of both parts a) and b). This will allow for data persistence and retrieval, ensuring that the information remains available even after the program execution ends.
By following these steps and utilizing the principles of object-oriented programming, inheritance, polymorphism, and file I/O in C++, we can create the necessary classes and achieve the desired functionality.

A small business, Mankato Computer Repairs (MCR), repairs smartphones, laptops, tablets, and computers. They have hired you to create a database to help run their business. When a customer brings a device to MCR for repair, data must be recorded about the customer, the device, and the repair. The customer's name, address, and a contact phone number must be recorded (if the customer has used the service before, the information already in the system for the customer is verified as being current). For the device to be repaired, the type of device, model, and serial number are recorded (or verified if the device is already in the system). Only customers who have brought devices into MCR for repair will be included in this system. Since a customer might sell an older device to someone else who then brings the device to MCR for repair, it is possible for a device to be brought in for repair by more than one customer. However, each repair is associated with only one customer. When a customer brings in a device to be fixed, it is referred to as a repair request, or just "repair," for short. Each repair request is given a reference number, which is recorded in the system along with the date of the request, and a description of the problem(s) that the customer wants fixed. It is possible for a device to be brought to the shop for repair many different times, and only devices that are brought in for repair are recorded in the system. Each repair request is for the repair of one and only one device. If a customer needs multiple devices fixed, then each device will require its own repair request. There are a limited number of repair services that MCR can perform. For each repair service, there is a service ID number, description, and charge. "Charge" is how much the customer is charged for the shop to perform the service, including any parts used. The actual repair of a device is the performance of the services necessary to address the problems described by the customer. Completing a repair request may require the performance of many services. Each service can be performed many different times during the repair of different devices, but each service will be performed only once during a given repair request. All repairs eventually require the performance of at least one service, but which services will be required may not be known at the time the repair request is made. It is possible for services to be available at MCR but that have never been required in performing any repair. Some services involve only labor activities, and no parts are required, but most services require the replacement of one or more parts. The quantity of each part required in the performance of each service should also be recorded. For each part, the part number, part description, quantity in stock, and cost is recorded in the system. The cost indicated is the amount that MCR pays for the part. Some parts may be used in more than one service, but each part is required for at least one service. A.

A. Create an ERD for the above business case. These business rules and assumptions help guide the design and functionality of the database, ensuring accurate and efficient management of repair requests, customers, devices, services, and parts.
An Entity-Relationship Diagram (ERD) is a visual representation of the entities, attributes, and relationships in a database system. It helps illustrate the structure and organization of the data. Here is the ERD for the Mankato Computer Repairs (MCR) business case:
[PDF containing the ERD for MCR]
The ERD depicts the entities: Customer, Device, Repair Request, Repair Service, and Part. It shows the attributes associated with each entity and the relationships between them. The Customer entity includes attributes such as name, address, and contact phone number. The Device entity includes attributes like device type, model, and serial number. The Repair Request entity has attributes such as reference number, request date, and problem description. The Repair Service entity includes service ID, description, and charge attributes. The Part entity contains attributes like part number, description, quantity in stock, and cost.
The relationships between entities are illustrated using lines connecting them. For example, the Repair Request entity is associated with the Customer and Device entities, indicating that each repair request is related to one customer and one device. The Repair Request entity is also associated with the Repair Service entity, showing that a repair request can involve multiple services. Finally, the Repair Service entity is connected to the Part entity, representing the parts used in each service.
**B. Provide business rules or assumptions, if any.**
In the Mankato Computer Repairs (MCR) business case, the following business rules or assumptions can be considered:
1. Only customers who bring devices for repair will be included in the system.
2. A customer may have multiple devices for repair, requiring separate repair requests for each device.
3. A device may be brought in for repair by more than one customer if it has been sold.
4. Each repair request is associated with only one customer.
5. Each repair request is for the repair of one device only.
6. The parts used in repairs are recorded, including their quantity in stock and cost.
7. Some repair services may not be required for any repair.
8. Some services require parts replacement, while others involve only labor activities.
These business rules and assumptions help guide the design and functionality of the database, ensuring accurate and efficient management of repair requests, customers, devices, services, and parts.

(a) Consider the time-complexity of an algorithm with respect to the problem size n being T(n) = 2T (In/2])+ n. Formally demonstrate that T(n) € 0(n-1gn). Full marks for using basic definitions and concepts, such as those found in lecture materials. (i) Prove via induction that T(n) has a function form of T(2³) = 2³ (T(1) + k). Hint: start with an appropriate variable substitution n = 2k, k € N₁, and iterate through k = 1,2,3, ... to discover the inductive structure of T(n). Full marks for precise mathematical statements and proofs for both the basis and induction step. [20 marks] (ii) Prove that T(n) € 0(n-lg n). You can use the multiplication rule with drop smaller terms directly without its formal construction, as well as apply other results as claimed in lecture materials. For the rest of your answer, justify any assumption you have to make. [16 marks] (iii) If this algorithm involves a partitioning process, what does 7(1) = 0(1) mean or suggest? [6 marks]
(i) T(n) = Θ(n^lg(n)) is proven using induction by showing that T(n) satisfies the basis step and the inductive step.
(ii) T(n) = Θ(n) is a valid conclusion when dropping the smaller term n from T(n) = Θ(n^lg(n)).
(iii) Θ(1) suggests that the partitioning process in the algorithm has a constant time complexity, meaning it does not depend on the problem size n.
(i) Proving T(n) = Θ(n^lg(n)) using induction:
Basis: For n = 2^3 = 8, we substitute n = 8 in T(n) = 2T(n/2) + n:
T(8) = 2T(8/2) + 8 = 2T(4) + 8
Assuming T(1) = c, where c is a constant:
T(8) = 2T(4) + 8 = 2[2T(2) + 4] + 8 = 4T(2) + 16 + 8 = 8T(1) + 16 + 8 = 8c + 16 + 8 = 8(c + 3) = 8(T(1) + 3)
So, the basis is satisfied.
Inductive step: Assume that T(k) = 2^k(T(1) + k) holds for all k ≤ n.
We want to prove that T(n+1) = 2^(n+1)(T(1) + n+1) also holds.
T(n+1) = 2T((n+1)/2) + (n+1)
= 2T(n/2) + (n+1)
Using the inductive hypothesis:
T(n+1) = 2[2^n(T(1) + n) + (n+1)]
= 2^(n+1)(T(1) + n) + 2(n+1)
= 2^(n+1)(T(1) + n+1)
So, the inductive step is satisfied.
By the principle of mathematical induction, T(n) = Θ(n^lg(n)).
(ii) Proving T(n) = Θ(n-lg(n)):
We already have T(n) = Θ(n^lg(n)) from the previous proof.
Using the property that n^lg(n) > n for n > 1, we can drop the smaller term n from T(n) = Θ(n^lg(n)):
T(n) = Θ(n^lg(n)) = Θ(n)
So, T(n) = Θ(n) is a valid conclusion.
(iii) If the algorithm involves a partitioning process and Ө(1) = Θ(1) is suggested, it means that the partitioning process has a constant time complexity. It implies that the partitioning operation does not depend on the problem size n and can be considered as a constant-time operation.

Using logism, create a time counter (using flipflops) that goes up with minutes and seconds using four 7-segment display. Show the truth table.
Logism is an educational application for designing and simulating circuits.
In this answer, we will create a time counter using flip-flops with four 7-segment displays to count minutes and seconds.The circuit design consists of two flip-flops.
The first one is the "Seconds Flip-Flop" which has a toggle or T flip-flop functionality, and it will count the seconds from 00 to 59. The second flip-flop is the "Minutes Flip-Flop" which has a divide-by-six function to count the minutes from 00 to 59. When the seconds flip-flop reaches 59, it will trigger the minutes flip-flop to count up by .
Then, the seconds flip-flop will reset to 00 and begin counting again.The input clock of the flip-flops is 1Hz. To make the circuit function properly, we need a decoder and four 7-segment displays. We will use the SN74LS47N BCD-to-7-Segment decoder/driver IC, which can decode a 4-bit binary input into a 7-segment display output.
Since we are using four 7-segment displays, we will need four decoder ICs and four displays.Each flip-flop has two outputs, Q and Q', which represent the binary digits of the seconds and minutes counters. We will connect the Q outputs of the seconds flip-flop to the least significant bits of the decoder ICs (A0, B0, C0, and D0), and the Q outputs of the minutes flip-flop to the most significant bits of the decoder ICs (A3, B3, C3, and D3).

In this example, the Bubble Sort algorithm is implemented to sort an array of integers. The array size and the array itself are defined in the `.data` section.
The program starts at the `main` label, where the array size is loaded into `a0` and the `bubble_sort` function is called using `jal`.
The `bubble_sort` function utilizes two nested loops. The outer loop iterates over each element of the array from `i=0` to `size-1`. The inner loop compares adjacent elements and swaps them if necessary.
The `swap` function is used to swap two elements in the array. It takes the address of the array as input and performs the swap operation.
After sorting the array, the sorted array is printed using the appropriate system call (`li v0, 4` and `syscall`). Finally, the program exits using the exit system call (`li v0, 10` and
`syscall`).
Note: Please make sure to assemble and run the code using a RISC-V assembler and simulator to observe the sorting result.

To sort the list of numbers in decreasing order by using Merge Sort, follow the below-mentioned steps: Algorithm of Merge Sort: Divide the array into two parts, the first half of the array, and the second half. In other words, calculate the middle of the array.
To sort the list of numbers in decreasing order by using Merge Sort, follow the below-mentioned steps: Algorithm of Merge Sort: Divide the array into two parts, the first half of the array, and the second half. In other words, calculate the middle of the array. Sort the first half of the array. Sort the second half of the array. Merge the sorted first and second halves. Step-by-step solution: The given list of numbers is {20, 31, 4, 10, 1, 40, 22, 50, 9}.To sort this list of numbers in decreasing order by using Merge Sort, we need to follow the steps as follows:
Step 1: First, divide the list of numbers into two equal halves: {20, 31, 4, 10, 1, 40, 22, 50, 9}
Divide the array into two parts, the first half of the array, and the second half. In other words, calculate the middle of the array. We get the below-mentioned two lists of numbers: {20, 31, 4, 10, 1} and {40, 22, 50, 9}
Step 2: Sort the first half of the array in decreasing order by using Merge Sort: First Half List: {20, 31, 4, 10, 1}
Divide the array into two parts, the first half of the array, and the second half. In other words, calculate the middle of the array. We get the below-mentioned two lists of numbers: {20, 31, 4}, {10, 1}
Now, we will sort the above-mentioned two sub-lists of the first half list of numbers: {20, 31, 4} and {10, 1}. Divide the sub-list {20, 31, 4} again into two sub-lists, i.e., {20, 31}, {4}. After that, divide the sub-list {10, 1} again into two sub-lists, i.e., {10}, {1}. Sort the above-mentioned four sub-lists. The sorted sub-lists will be {31, 20, 4}, {10, 1}. Now, Merge the above-mentioned sorted sub-lists. After merging, we get the sorted list of numbers of the first half, i.e., {31, 20, 10, 4, 1}
Step 3: Sort the second half of the array in decreasing order by using Merge Sort: Second Half List: {40, 22, 50, 9}
Divide the array into two parts, the first half of the array, and the second half. In other words, calculate the middle of the array. We get the below-mentioned two lists of numbers: {40, 22}, {50, 9}
Now, we will sort the above-mentioned two sub-lists of the second half list of numbers: {40, 22} and {50, 9}. Divide the sub-list {40, 22} again into two sub-lists, i.e., {40}, {22}. After that, divide the sub-list {50, 9} again into two sub-lists, i.e., {50}, {9}. Sort the above-mentioned four sub-lists. The sorted sub-lists will be {40, 22}, {50, 9}. Now, Merge the above-mentioned sorted sub-lists. After merging, we get the sorted list of numbers of the second half, i.e., {50, 40, 22, 9}
Step 4: Merge the sorted first and second halves: Now, merge the sorted first half list of numbers {31, 20, 10, 4, 1} and the sorted second half list of numbers {50, 40, 22, 9}. After merging, we get the sorted list of numbers {50, 40, 31, 22, 20, 10, 9, 4, 1} of the original list of numbers {20, 31, 4, 10, 1, 40, 22, 50, 9} in decreasing order.

Describe some of the problems with using a virus during pen testing.
Penetration testing (pen testing) is a crucial part of cybersecurity. The aim of a pen test is to find vulnerabilities in a system before an attacker does. However, using a virus in a pen test is not always the best approach, and it can come with several problems and risks.
A virus is malware that replicates itself by infecting other files and systems. Using a virus during pen testing could lead to unintended consequences, such as infecting other systems or even causing harm to the target system. Some of the problems with using a virus during pen testing are:1. Potential damage to systems: Pen testers who use viruses during their tests run the risk of damaging systems beyond repair. For example, if the virus causes a critical system component to fail, this can result in the system becoming unusable.2. Infection of other systems: Viruses can spread from the target system to other systems connected to the same network. If the virus infects other systems, this can lead to more significant issues and increase the risk of data loss or system downtime.3. Legal consequences: Using a virus in a pen test without proper authorization can result in legal consequences. Organizations need to obtain permission before performing any pen tests and have to adhere to specific guidelines to ensure the safety of the target system and other connected systems.
In conclusion, using a virus during pen testing has several drawbacks, such as potential system damage, infection of other systems, and legal consequences. Pen testers should explore alternative methods of identifying vulnerabilities in systems to minimize these risks. For example, ethical hackers can use non-invasive techniques such as port scanning and vulnerability scanning, which do not require the use of viruses. They can also use social engineering techniques to assess an organization's security posture. Ultimately, it is essential to understand the risks associated with using viruses during pen testing and take steps to mitigate them while still achieving the desired outcome of identifying vulnerabilities in systems.

Denitrification is the process of: removing nitrogen from organic matter converting ammonia to nitrate converting nitrate to nitrogen gas O converting ammonia and nitrite to nitrogen gas
Denitrification is the process of **converting nitrate to nitrogen gas**. It is a microbial process that occurs in soil, water, and sediment environments where oxygen is limited.
During denitrification, specialized bacteria use nitrate (NO3-) as an electron acceptor in the absence of oxygen. These bacteria convert nitrate into nitrogen gas (N2) through a series of enzymatic reactions. The process involves the reduction of nitrate to nitrite (NO2-), and further reduction of nitrite to nitric oxide (NO), nitrous oxide (N2O), and eventually to nitrogen gas.
This process is essential for the nitrogen cycle as it returns nitrogen gas to the atmosphere, completing the cycle by replenishing atmospheric nitrogen that can be used by plants and other organisms. Denitrification helps regulate the availability of nitrogen in ecosystems and plays a crucial role in balancing the global nitrogen cycle.
In summary, denitrification is the process of converting nitrate to nitrogen gas through the activity of specialized bacteria in oxygen-limited environments.

A guard band is a narrow frequency range between two separate wider frequency ranges to ensure that both can transmit simultaneously without interfering with each other. Assume that a voice channel occupies a bandwidth of 8 KHz and the whole bandwidth is 132 kHz. If we need to multiplex 16 voice channels using FDM, calculate the guard band in Hz.
Assuming that a voice channel occupies a bandwidth of 8 KHz and the whole bandwidth is 132 kHz, then using FDM the guard band in Hz is 4000 Hz.
FDM is the short form of Frequency Division Multiplexing. FDM is a modulation technique that can be used to combine multiple data streams into a single data stream to transmit them on a single channel. The data streams can be of varying types like voice, image, video, or any other type. One of the key components of FDM is the guard band. Let's understand what is a guard band.
A guard band is a narrow frequency range between two separate wider frequency ranges to ensure that both can transmit simultaneously without interfering with each other. It is also used to separate adjacent channels to avoid interference. The guard band is usually not used for transmission and remains unused.The given data:Bandwidth of voice channel, B1 = 8 KHz Total bandwidth, B2 = 132 KHz Number of voice channels, N = 16We know that the bandwidth required for N voice channels is given byB = N × B1 = 16 × 8 = 128 KHz. The remaining bandwidth is the guard band, G. Thus,G = B2 - B= 132 - 128= 4 kHz= 4000 Hz. Therefore, the guard band in Hz is 4000 Hz.

The outputs y₁ (t) and y2 (t) of these filters are multiplied to obtain the signal y(t) = y1 (1)y2 (1). (a) Sketch G₁ (f) and G₂ (f). (b) Sketch H₁ (f) and H₂(f). (c) Sketch Y₁(f) and Y₂(f). (d) Find the bandwidths of y₁ (t), y2 (t), and y(t).
The bandwidths of y₁(t), y₂(t), and y(t) can be determined by analyzing the frequency responses of the given signals and filters.
To sketch G₁(f) and G₂(f), we observe that G₁(f) represents the frequency response of g₁(t) and G₂(f) represents the frequency response of g₂(t). Since g₁(t) is an exponential function multiplied by the unit step function u(t), G₁(f) will have a single peak at f = 1000 Hz. On the other hand, g₂(t) is a linear function with a delay of 100 seconds, resulting in a linearly increasing frequency response, starting from f = 0 Hz.
To sketch H₁(f) and H₂(f), we use the given transfer functions H₁(f) = II(f/2000) and H₂(f) = (f/1000). H₁(f) is a low-pass filter that passes frequencies up to 2000 Hz, while attenuating higher frequencies. H₂(f) is a linear function that increases linearly with frequency.
For Y₁(f) and Y₂(f), we multiply the frequency responses G₁(f) and H₁(f) to obtain Y₁(f), and similarly, multiply G₂(f) and H₂(f) to obtain Y₂(f). Y₁(f) will have a single peak at f = 1000 Hz, and Y₂(f) will have a linearly increasing frequency response.
The bandwidth of y₁(t) is determined by the range of frequencies in Y₁(f) where the amplitude is significant. Similarly, the bandwidth of y₂(t) is determined by the range of frequencies in Y₂(f) with significant amplitude. The bandwidth of y(t) will depend on the overlap between the frequency ranges of y₁(t) and y₂(t).

Find V (t) for all time t. 4 V + 202 www t=0 t=0 7. 2 H + ww ΖΩ
For the given data, V(t) = (20/9)t Volts where V = voltage in the circuit.
The given circuit is a simple series circuit, therefore the current (I) is the same in both the resistor (4V) and the inductor (7.2H).
The inductor voltage is given by VL = L(di/dt)
Where L is the inductance, i is the current through the inductor and di/dt is the rate of change of current with respect to time t.
Substituting the given values into the equation we have, VL = 7.2(di/dt) Volts
Also, since the circuit is in series, the voltage across the inductor is equal to the voltage across the resistor.
We can write,VL = VR = 4V Volts
Hence,VL = 4V = 7.2(di/dt)
From the above equation, we can find the derivative of the current with respect to time as follows :
di/dt = (4/7.2) V/s = 5/9 V/s
Integrating both sides with respect to time t, we have : i = (5/9)t + C
where C is the constant of integration.
At t = 0, i = 0.
Hence, C = 0.
Substituting for i in terms of t, we have : i = (5/9)t Amps
Also, V = 4V
V (t) for all time t => V(t) = VL = VRV(t) = (5/9)t(4)VoltsV(t) = (20/9)t Volts
Therefore, V(t) = (20/9)t Volts.
Thus, for the given data, V(t) = (20/9)t Volts.

Use a FOR loop to read the N entries from the user and display the SUM and AVERAGE of these entries.
Here's the main answer you can refer to the Scilab code and implementation for the given problem:
Code for Scilab:
ID = 613362;
N = str2double(msprintf("%d",ID(1)));sum = 0;for i=1:
N x = input(msprintf("Enter number %d: ", i)); sum = sum + x;endaverage = sum/N;disp(msprintf("SUM = %d, AVERAGE = %d", sum, average));
In the first step of the code, the given ID is taken as an example. We take the first digit of the ID and convert it to a number using msprintf. Then, we use str2double to convert it to a numeric value.
Next, we set the variable 'sum' to zero. We then enter a for loop that runs N times (where N is the first digit of the ID). For each iteration of the loop, we use the
to prompt the user to enter a number. We then add that number to the 'sum' variable.
The last step of the loop is to calculate the average, which is simply the sum divided by N. We then display the SUM and AVERAGE using msprintf and disp.

Given that the operation is subtraction and the numbers to be subtracted are -10 and -12. Let's convert them to binary using 5-bit two's complement system.-10 in binary is 10110-12 in binary is 10100Subtracting 10 from 12 we get,00110.
Now to find the two's complement, we can invert the bits and add 1. So,-12 = 01011 + 1 = 01100-10 - 12 = 00110 + 01100 = 10010The result in binary is 10010. Since this is a 5-bit two's complement system, the leftmost bit is the sign bit. A 1 in this bit position indicates a negative number. In this case, the leftmost bit is 1, indicating that the result is negative. The magnitude of the result is 0010, which is 2 in decimal.
Hence, the result of -10 - 12 in 5-bit two's complement system is -2.There will be no overflow/underflow as the magnitude of the result is less than 16 (10000 in binary), which is the largest number that can be represented using 5-bit two's complement system.

Two water columns are at different temperatures, one being at 35oC and the other being at 180C. The water columns are separated by a glass wall of area 1m by 2m and a thickness of 0.005m. Calculate the amount of heat transfer. (Thermal Conductivity of glass is 1.6 W/mK)
The amount of heat transfer between the two water columns through the glass wall is -54,400 watts (or -54.4 kilowatts).
To calculate the amount of heat transfer between the two water columns through the glass wall, we can use the formula for heat transfer:
Q = (k * A * ΔT) / d
Where:
Q is the amount of heat transfer
k is the thermal conductivity of the glass
A is the area of the glass wall
ΔT is the temperature difference between the two water columns
d is the thickness of the glass wall
Given:
k = 1.6 W/mK
A = 1m * 2m = 2m²
ΔT = (18°C) - (35°C) = -17°C (temperature difference, taking into account the direction of heat transfer)
d = 0.005m
Plugging in these values into the formula:
Q = (1.6 W/mK * 2m² * -17°C) / 0.005m
Q = -54,400 W
The negative sign indicates that heat is transferred from the hotter water column to the colder water column. Therefore, the amount of heat transfer between the two water columns through the glass wall is -54,400 watts (or -54.4 kilowatts).

A token bucket mechanism generates tokens with a constant rate r = 14 tokens/second. The bucket depth is b = 19 tokens. A packet requires one token to be transmitted. Assume that the bucket is full at the start, and the input and output links of this mechanism have infinite capacities. What is the number of transmitted packets after a time interval t = 2 seconds? Note: Enter your result as an integer in the answer box. Answer:
A token bucket mechanism is a mechanism that regulates the rate at which a system processes requests. Tokens are produced at a constant rate of r = 14 tokens/second in a token bucket mechanism.
The bucket depth is b = 19 tokens, and a packet requires one token to be transmitted. Assume the bucket is full at the links of this mechanism have infinite capacity. We need to find the number of transmitted packets after a time interval t = 2 seconds.
The total number of tokens generated in 2 seconds is 14 * 2 = 28 tokens. Since the maximum capacity of the bucket is 19, the number of tokens that can be stored in the bucket is 19. Hence, the number of packets that can be transmitted interval t = 2 seconds is 19.Answer.

We assume that a LAN network has 4 hosts (A, B, C and D), and host A is the security administrator's host and wants to the promiscuous mode. Can the below ARP packet be used fort that task? ARP operation 1 Source IP A Source MAC B Destination IP с Destination MAC 0 Destination MAC FF:FF:FF:00:00:00 Source MAC A MAC type (IP or ARP) ARP 1. Yes 2. NO
Promiscuous mode is a type of network card setting in which the NIC passes all frames to the host that are in its segment, even if they are intended for another system. Therefore, it can be used to monitor the network for suspicious activities and check for any unauthorized access.
A host in a Local Area Network (LAN) network can be put in promiscuous mode using a network protocol known as the Address Resolution Protocol (ARP).In the given scenario, it is possible to use the provided ARP packet to put the host A in promiscuous mode.
The reason is that this packet is an ARP request that includes information on source IP address, source MAC address, destination IP address, and the destination MAC address. To put the host A in promiscuous mode, it is required to put a fake MAC address of FF:FF:FF:00:00:00 in the ARP packet, which is shown as the destination MAC address.
The ARP packet given in the scenario contains the destination MAC address of 0, which is incorrect. Therefore, the correct answer to the question is "NO".Hence, the answer is option 2. NO.
