The defense mechanism that is used by a person who constantly blames their unbearable feelings on another person is called Projection.

To understand and arrive at this answer, it is important to have a basic understanding of defense mechanisms. Defense mechanisms are psychological strategies that people unconsciously use to protect themselves from uncomfortable or threatening thoughts, feelings, or impulses.

In the case of projection, it occurs when someone attributes their own undesirable thoughts, feelings, or impulses onto someone else. They transfer their own unacceptable behavior or feelings onto another person, essentially "projecting" their own issues onto someone else.

In this scenario, when someone constantly blames their unbearable feelings on another person, they are using projection as a defense mechanism. By attributing their difficult emotions or issues to someone else, they are able to avoid taking responsibility for their own behavior or emotions.

Therefore, the correct answer is:

D. Projection
