Answer:
The answer is A. Conformity.
Step-by-step explanation:
The term conformity is used in social psychology to explain a type of social influence on an indivudual's behavior or decisions. According to social psychologists, conformity is a change of behavior in order to adapt to the behavior of the majority and, in consequence, to fit in. Conformity is also commonly known as group pressure.
