Explanation:

Projection: In psychology, the term "projection" is referred to as one of the defense mechanisms which was proposed by Sigmund Freud in his theory of psychoanalysis. An individual subconsciously uses the "psychological projection" to cope-up with different emotions or feelings that are being considered as difficult.
