Answer:
b.
Step-by-step explanation:
If you witness something that is of great importance, or great distraught then you have a responsibility to respond to what is going on. You have a responsibility to talk about how bad or good it was. In this situation he had a responsibility to discuss how bad it was, in which he saw. If he does not then as a bystander it makes him almost as bad as the person doing the wrong. Think about it like this if you witness a bully bullying someone and you don't say a thing then that makes you just as bad as the bully, because you are essentially letting them get away with the bad the have done. Your just aiding what it is they are doing pretty much.
