________ is the condition of being arranged in social strata or classes within a group.

Correct option is A

The correct answer is (a) Social Stratification
Explanation:
Social stratification is a sociological term describing the hierarchical arrangement of individuals into social classes or strata based on factors like wealth, power, and status. It creates a system of inequality where some groups have more access to resources than others.
Information Booster:
● Hierarchy: Stratification creates a vertical ranking in society, often visualized as a pyramid with fewer people at the top.
● Bases of Stratification: Common criteria include income, occupation, education, caste, or race.
● Educational Impact: A student's position in the social strata often determines the quality of schooling and resources they can access.
● Stability: Stratification systems tend to persist over generations, often passed down through family inheritance and social networks.
● Universal Phenomenon: Almost all complex societies exhibit some form of stratification, though the criteria may vary.
Additional Points:
● Option (b): General term – While similar, 'classification' is a broader term for grouping, whereas 'stratification' specifically implies a hierarchy.
● Option (c): Psychological state – This refers to an individual's feeling of being accepted and included in a group.
● Option (d): Balanced state – Social equilibrium refers to a state of stability and harmony within a social system, not its layers.

So the correct answer is (a)
