If people wrinkle their noses in disgust when presented with a strange-looking food,they are likely to experience an increasingly intense emotional aversion to the food.This best illustrates

A) egocentrism.
B) nonverbal communication.
C) a genetic predisposition.
D) the facial feedback effect.

The scenario described in the question is an example of the facial feedback effect, which suggests that our facial expressions can actually influence our emotional experiences. In this case, the wrinkling of the nose in disgust may intensify the individual's aversion to the food. Egocentrism and genetic predisposition are not directly relevant to the scenario, whereas nonverbal communication is a factor but not the best fit as the question is asking for a specific phenomenon.
