Jane was involved in an automobile accident in which both her parents were killed. When you ask her about it, she says she has no memory of the accident. What ego defense mechanism is she using?

The correct answer is - repression

Explanation:

There are many types of defense mechanism like repression, denial, projection, displacement, regression, etc. Repression is an unconscious defense mechanism that is ego employed to keep out the bad and threatening thought to come in mind.

So here when Jane is asked about the accident she says that she is not having any memory about the accident which shows that she is using repression as an ego defense mechanism to avoid that disturbing thought of accident to become conscious.
