Step 1: Understanding the Concept:
The solution will address the question based on caste stratification. The question asks for the ideological basis of the caste system.
Step 2: Detailed Explanation:
The caste system is a form of social stratification where social position is ascribed at birth. The ideological justification for this rigid, hierarchical system is deeply rooted in Hindu religious and philosophical concepts.
- (A) Punarjanma (Rebirth): This doctrine, along with the concept of Karma, provides the fundamental justification for one's birth into a particular caste. It holds that one's position in this life is a direct consequence of their actions (karma) in a previous life. This belief legitimizes the hierarchy and encourages conformity.
- (B) Chaturvarna is the four-fold structural model of the system, not its ideological basis.
- (C) Varnashram refers to the system of varna and ashrama (stages of life).
- (D) Gotra refers to lineage or clan and is primarily related to marriage rules (exogamy).
Step 3: Final Answer:
The ideological justification for the caste stratification system is based on the doctrine of Punarjanma (rebirth) and Karma.
