Answer:
D. memories of the last panic attack
Explanation:
A classical conditioning can be defined as a learning process that is happens or that is as a result of two stimuli's connection.
For example, if a dog bites a boy, anytime the boy sees any dog, he will being to panic as a result of the previous experience. This means the boy's sense of panic is always triggered once he sees a dog whether the dog is close-by or faraway.
Just like in the question, panic attacks can be triggered ahead of bodily changes as a result of being accustomed to a certain stimuli.
