Your friend Mary became very ill a few hours after eating fried chicken in the college cafeteria. Now, Mary feels queasy whenever she smells fried chicken. Having read the learning chapter in your psychology class, you explain that:

A. latent learning has occurred and she can overcome the queasy feeling by forcing herself to eat fried chicken.
B. she has been negatively reinforced for eating fried chicken, because consuming it led to an aversive consequence.
C. she has experienced a learned taste aversion, which can occur after only one pairing of food and illness.
D. since she only experienced one pairing of the fried chicken and illness, her queasy feelings cannot be a classically conditioned response.
