This question lacks options, options are:

B. Diffusion of responsibility
C. Deindividuation
D. Groupthink
The correct answer is B.
Step-by-step explanation:
Diffusion of responsibility occurs when people have to make a decision, but wait for other people to do it first, that is, it is the phenomenon by which a person feels less responsible for intervening in an emergency to help the victim when there are other people present than when he/she is the only witness. The reasoning that inhibits helping behavior is that surely someone else will help. Diffusion of responsibility focuses on the fact that when there are multiple observers, the responsibility is divided among all and as a result no one helps.
