B) The person sees a victim and there are many others around.

In option C, the person is in close proximity to the victim and the situation requires immediate action, making it less likely that they will do nothing. In options A, B, and D, the person may not feel an immediate sense of responsibility or urgency to act, making it more likely for them to do nothing.
