Answer:
Steve's costs are greater than his rewards.
Explanation:
The Social Exchange Theory, as it's name suggests, uses a cost-benefit analysis, which determines outcomes and relationships measured in costs, benefits and rewards from any type of interaction between two parties. This theory is used by both sociologists and psychologists to study the behavior of the two selected parties, groups or individuals. Now, in this case, Steve's costs are greater than his rewards given that he makes the effort to surpise Marla, going out of his way to try and make her happy. But, given that he feels that he is taken for granted, one could argue that, effectively, his costs are greater than his rewards.
The correct answer is option A. It is true that communication between members of a primary group is emotional, personal and satisfying. People belong to primary groups such as a family or having close friends, to satisfy their personal needs of belonging and fulfillment. The members of a primary group are close, take care of each other and share activities.
