Which defense mechanism is correctly matched with a definition? reaction formation—unacceptable impulses are channeled into socially acceptable activities projection—unacceptable impulses are expressed as their opposites displacement—an unwanted feeling is redirected from a threatening individual to a less threatening one sublimation—unacceptable impulses are attributed to another person?

The answer would be: Displacement—an unwanted feeling is redirected from a threatening individual to a less threatening one

Defense mechanism tells how a person will react to an unacceptable condition. There are a few defense mechanisms with different levels of pathological, immature, neurotic and mature. Displacement is one of the neurotic levels that shift a dangerous aggression into a less threatening one.
