Step 1: Identify the theory. Modernization theory (e.g., Rostow, Parsons) argues that poorer countries can achieve convergence by adopting Western capitalist institutions, values, and stages of development.
Step 2: Eliminate alternatives. Postmodern and Subaltern frameworks critique such narratives; Marxist theory emphasizes class conflict and dependency, not emulation of Western capitalism.
Final Answer: (D) Modernization
