Step-by-step explanation:
The defense mechanism described in the question is projection. Projection is a defense mechanism where a person denies their own unconscious feelings and attributes them to someone else. It involves attributing the source of thoughts, feelings, and behaviors to others or to outside influences to relieve oneself of responsibility and alleviate anxiety.
For example, if someone is feeling angry but does not want to acknowledge it, they might project that anger onto another person by accusing them of being angry. This allows the person to avoid taking responsibility for their own feelings.
