Verified step by step guidance

1. Understand the concept of the reciprocity norm in social psychology, which refers to the social rule that suggests people feel obligated to return favors or kindnesses that others have done for them.
2. Review each option carefully and identify whether it involves the idea of returning a favor or responding to an action with a similar action.
3. Recognize that 'Conforming to group pressure to fit in' relates more to social conformity rather than reciprocity.
4. Note that 'Helping others without expecting anything in return' describes altruism, which is different from reciprocity because it lacks the expectation of return.
5. Identify that 'Returning a favor to someone who has helped you' directly reflects the reciprocity norm, as it involves responding to a positive action with another positive action.
