Step 1: Understanding Bougle’s theory on the caste system.
Celestin Bougle focused on the concept of mutual repulsion between castes as a defining feature of the caste system. He argued that this repulsion is reflected in various social practices that maintain caste boundaries.
Step 2: Analyzing the options.
- (A) Incorrect, while upward mobility is restricted within the caste system, Bougle's theory emphasizes the structural and social practices that enforce separation rather than mobility.
- (B) Correct, endogamy (marriage within the same caste) is a key practice that reflects caste separation and mutual repulsion.
- (C) Incorrect, Westernization, though influencing caste dynamics, is not directly tied to the mutual repulsion Bougle describes.
- (D) Correct, commensal restrictions (restrictions on sharing food between castes) are another manifestation of caste separation and repulsion.
Step 3: Conclusion.
The correct answers are (B) Endogamy and (D) Commensal restrictions, as they reflect the structural barriers and mutual repulsion inherent in the caste system.
