Answer: A
Motivated forgetting
Explanation: Motivated forgetting is a psychological behavioral theory that cites that some people may forget unwanted memories consciously or unconsciously to reduce the anxiety or pain that the memory brings.
This can be said to be a defense mechanism since this deliberate or unconscious behavior reduces the fear or supposed harmful impulses that could arise from remembering that event. hence it can sais that Eric choose to forget his childhood and events that happens then because it causes him pain.
