**Question:** All of the following are defence mechanisms of ego except

A. Repression
B. Sublimation
C. Regression
D. Reaction formation

**Core Concept:**
The defense mechanisms of ego are psychological coping strategies employed by an individual to defend against anxiety-provoking internal and external stimuli. These mechanisms are part of the personality structure known as the "ego," which seeks to maintain equilibrium between the id (primitive, impulsive desires) and superego (moral conscience and societal norms).

**Why the Correct Answer is Right:**
The correct answer, **Option A: Suppression (Repression)**, is excluded from the defense mechanisms of ego because it refers to the unconscious rejection of distressing thoughts, memories, and impulses. While repression is a defense mechanism, it is not considered part of the ego defenses as it does not involve conscious modification or compromise between the id and superego.

**Why Each Wrong Option is Incorrect:**

**Option B: Sublimation** is a defense mechanism where an impulse or desire is redirected from its original, potentially unacceptable aim into an apparently acceptable one, contributing to the ego's growth and development. This option is part of the defense mechanisms of ego.

**Option C: Regression** refers to a temporary return to a previous psychosexual stage in the development of the personality. Although regression is also a defense mechanism, it involves a regression in psychosexual development stages, not specifically related to the ego defenses.

**Option D: Reaction Formation** is a defense mechanism where an individual unconsciously opposes an unacceptable idea, impulse, or feeling by adopting the opposite standpoint. This option is part of the defense mechanisms of ego.

**Core Concept:**
The defense mechanisms of ego, also known as conscious defenses, help maintain psychological equilibrium by redirecting, denying, or rationalizing distressing experiences, thoughts, and impulses.

**Why Each Wrong Option is Incorrect:**

**Option A: Suppression (Repression)** is not part of the defense mechanisms of ego. It is considered a primitive defense mechanism that occurs at the unconscious level, while the correct answer, **Option B: Sublimation**, belongs to the defense mechanisms of ego as it involves redirecting impulses or desires towards socially acceptable goals.

**Option C: Regression** is a broader concept, relating to a regression in psychosexual development stages, while the correct answer, **Option D: Reaction Formation**, belongs to the defense mechanisms of ego by opposing unacceptable ideas or feelings with their opposite standpoint.

**Option A: Suppression (Repression)** is not part of the defense mechanisms of ego as it occurs at the unconscious level, whereas the correct answer, **Option B: Sublimation**, belongs to the defense mechanisms of ego by redirecting impulses or desires towards socially acceptable goals.
