Answer:
A. Reception
Read Explanation:
Defense mechanisms are unconscious psychological strategies used by the ego to cope with anxiety and protect oneself from unpleasant thoughts, feelings, or reality.
Repression, Reaction formation, and Rationalisation are all well-established and commonly recognized defense mechanisms in psychology.
Repression: Unconsciously blocking out painful or unacceptable thoughts and feelings from awareness.
Reaction formation: Behaving in a way that is the opposite of one's true, often unacceptable, feelings.
Rationalisation: Justifying unacceptable behaviors or feelings with seemingly logical reasons to avoid the true, often uncomfortable, reasons.
Reception is not a term used to describe a defense mechanism in psychology. It generally refers to the process of receiving or accepting something, or in a more technical sense, how cells detect and respond to external signals (in biology).
