D. The process of stripping someone of their identity.

Explanation:

The term individual comes from Latin word "individuus" meaning indivisible or inseparable. In English, today, it means one, single, separate object or a person.

So, in analogy to this, deindividuation is a term meaning losing oneself's identity and individual characteristics to a group.

The participants in this Stanford Prison Experiment lost all of their individual traits; they gained characteristics of the group they belonged to (prisoners or guards) and acted in the way it was expected of them, not the way they would normally do.

for this, you need to remember something significant in your own life, for example, if you were bullied when you were younger, you can mention your memories on this and touch on how such treatment can harm other kids your age either physically or mentally. (racism, car crashes, a parent in the hospital are all very good subjects, think hard on it! )
