A. Control group
B. Cohabitation
C. Closed system
D. None of these
🧠 Explanation:
A closed system in sociology has little to no individual mobility, like caste systems. For sociology students, this highlights social structures, making it a key topic for studying societal hierarchies, class systems, and social dynamics. It restricts upward movement. Understanding this clarifies social rigidity. It’s essential for analyzing social systems, inequality, and societal change. Studying closed systems offers insights into how societies limit mobility, crucial for sociology, anthropology, and social sciences, ensuring knowledge of structural barriers and their impact on individual opportunities and societal evolution.
