Repression Is a Defense Mechanism Characterized by the Ego

Repression is a defense mechanism characterized by the ego:

A) blocking external events from consciousness because they are too threatening.
B) hiding your id impulse in the unconscious to keep you unaware of it.
C) retreating to an earlier time in your life when the current stressor was absent.
D) coming up with seemingly acceptable explanations for behaviors actually based on id impulses.
