Final answer:
The size of a crowd and helping behavior are inversely related.
Step-by-step explanation:
The question is asking about the relationship between the size of a crowd and helping behavior. The correct answer is a) Inversely related. This means that as the number of bystanders increases, people are less likely to help someone in distress. This phenomenon is known as the bystander effect, where individuals are less likely to intervene in an emergency if there are others present.
The bystander effect occurs because people feel a diffusion of responsibility when there are others around. They assume that someone else will take action or that someone else has already helped. This diffusion of responsibility leads to a decreased likelihood of helping behavior.
For example, if you witness someone having a seizure on the way to class and there are several other students around, you may be less likely to help because you assume someone else will. However, if you are the only one around, you are more likely to take action and provide assistance.
