Vanessa ordered pizza from a national pizza chain and became very ill immediately after eating the pizza. Years later, Vanessa still feels uneasy when she sees an advertisement for the pizza chain or drives by one of its establishments. In this example, the conditioned stimulus is the:

pizza establishment.

Explanation:

Based on the scenario being described within the question it can be said that in this situation the conditioned stimulus is the pizza establishment. That is because a conditioned stimulus is neutral stimulus that triggers a conditioned response after it has been associated with an unconditioned stimulus. Therefore in this scenario the conditioned stimulus is the pizza establishment which causes Vanessa to feel sick every time she sees it (conditioned response).
