A. Pluralistic ignorance

Explanation:

Pluralistic ignorance refers to how eventhough we may all behave the same way but inwardly think that others are behaving that way for different reasons than ours as a result we end up going along with them thinking they feel the opposite of what we feel.

The assumption that our classmates are quite because they understood the lecture instead of thinking that maybe they also may be afraid to ask is what makes up the pluralistic behavior.

We end up going along with an idea thinking that the majority of people agrees with that idea only to find than non of them agrees with it.
