Step 1: Understanding the Concept:
Self-concept refers to the dynamic cognitive representation an individual holds of themselves, incorporating physical, social, and psychological traits.
Step 2: Detailed Explanation:
- Assertion (A): Self-concept is a subjective mental image of oneself. It encompasses self-perceptions of one's identities, talents, personality, limits, and roles in life. This makes Assertion (A) correct.
- Reason (R): Self-concept is not constructed in isolation. According to major psychological frameworks (including Leon Festinger's Social Comparison Theory and Charles Cooley's Looking-Glass Self), self-concept is deeply influenced by social comparisons with peers and feedback from the social environment, especially during childhood and adolescence. Therefore, stating that self-concept is formed "without social comparison" is factually incorrect.
Step 3: Final Answer
Since Assertion (A) is correct and Reason (R) is wrong, the correct choice is option (C).
