Nature And Formation Of Groups

The Correct Option is (B): D. A. B. E. C

Step 1: Understanding the Concept:
This question requires matching key concepts from group dynamics with their correct definitions.

Cohesiveness: The degree to which group members are attracted to each other and are motivated to stay in the group; the "we-feeling".
Status: A socially defined position or rank given to groups or group members by others.
Roles: A set of expected behavior patterns attributed to someone occupying a given position in a social unit.
Group Polarisation: The tendency for a group's initial average opinion to become more extreme following group discussion.
Step 2: Detailed Explanation:
Let's match each term from List-I to its definition in List-II:

(A) Cohesiveness directly corresponds to (IV) "Togetherness or mutual attraction among group members."
(B) Status matches with (III) "Relative position given to group members by others."
(C) Roles correctly pairs with (II) "Socially defined expectation that are expected to be fulfilled."
(D) Group polarisation is defined by (I) "Strengthening of group's initial position as a result of group interaction and discussion."
Step 3: Final Answer:
The correct matching is (A)-(IV), (B)-(III), (C)-(II), and (D)-(I). This combination is found in option (4).
