Mark is angry when the teacher blames him for misbehaving when it actually was the child behind him who had been acting up. As he leaves after school, he shoves another boy who gets in his way. Freud would say that Mark is unconsciously using the defense mechanism of:

A) displacement.
B) repression.
C) projection.
D) denial.

Defense Mechanism

Psychological strategies brought into play by individuals, groups, and even nations to cope with realities and to maintain self-image.

Displacement

A defense mechanism where an individual redirects emotional impulses from a real object to a substitute target.

Repression

A defense mechanism where unpleasant thoughts, feelings, or desires are unconsciously excluded from consciousness.
