The correct answer is Option 3: (A)-(III), (B)-(IV), (C)-(I), (D)-(II).
The correct match of the theories with their corresponding researchers/authors is:
(A) Theory of planned behaviour → (III) Ajzen & Fishbein: The Theory of Planned Behavior was proposed by Ajzen and Fishbein. It focuses on how attitude, subjective norms, and perceived behavioral control influence an individual's intention and behavior.
(B) Theory of causal attribution → (IV) Kelley: Kelley’s theory of causal attribution suggests that people make causal attributions to explain others' behaviors based on three factors: consensus, consistency, and distinctiveness.
(C) Social identity theory → (I) Tajfel: Social Identity Theory was developed by Henri Tajfel and focuses on how individuals derive their identity from social groups, affecting intergroup behavior and prejudice.
(D) Contact hypothesis → (II) Pettigrew: The Contact Hypothesis was developed by Gordon W. Allport and later expanded by Pettigrew, suggesting that contact between groups can reduce prejudice, particularly under favorable conditions.
