Answer:
-lying
Explanation:
As the name implies, prosocial behavior is behavior that benefits other people. What are ways that you can help people other than yourself? Also, you could just take an educated guess for this question. Just look for the one answer that is different from the others. Let's take a look at the answers:
Sharing: This is definitely prosocial. Sharing is caring.
Lying: This isn't prosocial. Even though sometimes lying could benefit others, usually it doesn't. This does not benefit others.
Working hard: This is prosocial. Working hard shows that you care for other people.
Being kind: This is obviously prosocial. Being kind can make people like you, because you are being nice to them.
The answer is lying. This is the odd one out, the only answer with almost no way of helping others.
