List - I	List - II
(A) World System Theory	(I) Kenneth Waltz
(B) Social Constructivism	(II) John Mearsheimer
(C) Defensive Realism	(III) Immanual Wallerstein
(D) Offensive Realism	(IV) Alexander Wendt

Choose the correct answer from the options given below: 

Correct option is B

The correct answer is (b) (A)-(III), (B)-(IV), (C)-(I), (D)-(II). Here's how the theories and theorists correspond:
· World System Theory (A)-(III): This theory, introduced by Immanuel Wallerstein, emphasizes the global division of labor and the role of capitalism in structuring international relationships, with a focus on core, semi-periphery, and periphery states.
· Social Constructivism (B)-(IV): Alexander Wendt is a major figure in constructivism, which argues that international relations are socially constructed rather than purely material or objective.
· Defensive Realism (C)-(I): Kenneth Waltz is a proponent of defensive realism, which suggests that states seek security through balance rather than aggressive expansion, emphasizing a systemic structure that maintains stability.
· Offensive Realism (D)-(II): John Mearsheimer is known for offensive realism, positing that states are inherently aggressive in their pursuit of power for survival in an anarchic international system.
Information Booster
1. World System Theory classifies countries as core, semi-periphery, and periphery based on economic roles and power within the global system.
2. Social Constructivism posits that identities, norms, and interactions shape the structure of international politics, challenging purely materialist theories.
3. Defensive Realism holds that states prioritize survival and view power accumulation as a means of deterrence rather than aggression.
4. Offensive Realism argues that an anarchic international system compels states to seek dominance to ensure security, often leading to conflict.
5. Immanuel Wallerstein developed World System Theory as a critical theory analyzing historical developments and inequalities in global capitalism.
6. Alexander Wendt's constructivism introduced a significant shift in IR, arguing “anarchy is what states make of it,” implying that international norms are flexible.
