Answer:
The answer is a. conditioned response.
Explanation:
In classical conditioning, a conditioned stimulus (the parks) is associated with an unrelated consequence, called unconditioned stimulus (the incidences of violence). This produces a reaction known as conditioned response (the fear of parks).
It's important to recognise that any neutral stimulus can become conditioned. In this example, Jessica would probably be afraid of banks if she had heard about violent events in there.
