Concept:
Social stratification is a core sociological concept examining how societies rank categories of people in a hierarchy based on various theoretical foundations.
Step 1:
Talcott Parsons argued that social stratification is rooted in a society's system of shared norms. He proposed that stratification is a reflection of how a society evaluates different roles based on its shared values (III).
Step 2:
Davis and Moore are famous for their functionalist theory, which argues that social stratification is a functional necessity (IV) required to ensure the most capable people fill the most important positions.
Step 3:
Melvin Tumin wrote a famous critique of the Davis-Moore thesis, emphasizing that extreme stratification can interfere with role allocation and performance (I) by limiting educational and training opportunities for lower strata.
Step 4:
G.S. Ghurye, a pioneer of Indian sociology, focused extensively on the unique structural peculiarities of the Indian social system, specifically the caste hierarchy (II).
Step 5:
Matching these theorists to their specific concepts results in the sequence: A-III, B-IV, C-I, D-II.
Step 6:
This sequence aligns with option (4), which provides the correct theoretical pairings.
$$\boxed{\text{(4) A-III, B-IV, C-I, D-II}}$$
