The door to the men's restroom originally did not cause any reaction in Matt, as it was not a stimulus that he associated with feeling nauseated. However, after repeatedly cleaning the men's restroom and feeling sick, the door became a conditioned stimulus that elicited a conditioned response of feeling queasy. Therefore, the best answer is D) conditioned stimulus.
