b) group polarization.
c) social facilitation.
d) social loafing.

Mia's behavior is an example of - A) conformity.

Explanation:

Conformity is a form of social behavior that is one of the most common in society, where individuals match their attitude and behavior with the group in order to fit in.

Here, Mia conforms to sorority's choices (group), because it is easier and safer to follow the path laid by others, rather than making a decision themselves and creating a new path. This behavior would put a person into a risk of exclusion, which is even higher with groups that share a strong self identity, like sororities.
