One type of evidence supporting the James-Lange theory of emotions is that

A) young children have the same facial expressions of emotion as adults.
B) people with pure autonomic failure experience stronger than normal emotions.
C) molding someone's face into a smile or frown enhances the relevant emotion.
D) emotional expressions vary sharply from one culture to another.

The James-Lange theory of emotions suggests that physiological arousal precedes the experience of emotion, and one piece of evidence supporting this theory is that manipulating facial expressions (such as molding someone's face into a smile or frown) can enhance the corresponding emotional feeling. This is because, according to the theory, the physical changes in the body are part of what leads to the emotional experience.
