The classical conditioning pathway is depicted in the following scenario. The correct option is B.
In this scenario, Lionel's fear of small spaces was likely a result of classical conditioning. The reading of the Edgar Allen Poe story served as the unconditioned stimulus (UCS), which naturally evoked fear and anxiety in the teacher.
The classroom environment and the presence of small spaces like desks and chairs could be considered neutral stimuli (NS). After repeated exposure to the story in the presence of the classroom environment, Lionel may have learned to associate the fear and anxiety of the teacher with the classroom environment and small spaces, leading to the development of a conditioned response (CR) of fear and anxiety in those situations.
Thus, the ideal selection is option B.
