According to Freud,defense mechanisms are used by the

A) id to defend against the accusations and guilt feelings produced by the superego.
B) ego to prevent threatening impulses from being consciously recognized.
C) superego to prevent expression of sexual and aggressive drives.
D) id,ego,and superego in a repetitive sequence of internal conflicts.

According to Freud, defense mechanisms are unconscious strategies used by the ego to prevent threatening impulses, thoughts, or feelings from being consciously recognized and causing anxiety. The id is the source of these impulses, and the superego is the internalized moral code that evaluates and judges behavior, but it is the ego that mediates between them and the external reality. Therefore, defense mechanisms serve to protect the ego from the conflicts and demands of the id and the superego, which can be overwhelming and conflicting.
