Sociologist Gouldner (1960) contended that the norm of reciprocity is as universal as the incest taboo.
Answer: Option C
<u>Explanation:</u>
The concept of norm of reciprocity stands for that the people who have done some thing for us or have helped us in any manner, their favor should be returned for their doing.
We should be very kind to them in repaying their favor and paying off their obligation. It is expected by all the people that all the people in the world respond favorably to each other and by returning benefits for the benefits done by them for us. This is universal.
