Charity used to really enjoy potato salad, so at a family reunion, she ate a large helping. Unfortunately, the potato salad had not been kept cold, and Charity became quite ill after eating it. Now she finds that even the sight of potatoes in the grocery store can make her feel sick to her stomach. In this example, the sick feeling Charity experiences when she sees potatoes in the grocery store is
A. an unconditioned response.
B. an unconditioned stimulus.
C. a conditioned stimulus.
D. a conditioned response.

D) Conditioned response.

Explanation:

Conditioned response is the triggered response that is generated when a conditioned response gets linked with an unconditioned response.

According to the question,as Charity has fallen sick due to potato , she experiences a trigger in her stomach due to conditioned response from sight of potato that generates conditioned response in form of sick feeling in stomach.

Other options are incorrect because unconditioned response, conditioned stimulus and conditioned response is not depicted through sick feeling that Charity gets after seeing potatoes.Thus, the correct option is option(D).
