Henry is very shy and withdrawn. He rarely acts on impulse, feels guilty about any display of desire, and is emotionally restricted. Freud would say Henry's ________ is the dominant part of his personality.

A) id
B) sexual instinct
C) superego
D) ego

The superego is the part of the personality that represents the internalized ideals and values of society, as well as the individual's own internalized morals and standards. It is responsible for inhibiting impulses and promoting socially acceptable behavior. Henry's behavior of feeling guilty about displays of desire and being emotionally restricted are indicative of a dominant superego in his personality.
