The distinction between prescriptive norms and proscriptive norms lies in the types of behaviors they influence:

Prescriptive Norms:

Encourage behaviors considered positive or desirable by the group.

Example: Encouraging collaboration and teamwork.

Proscriptive Norms:

Discourage behaviors considered negative or undesirable by the group.

Example: Prohibiting dishonesty or discrimination.

Why Other Options Are Incorrect:

A: Both types of norms can be mandatory depending on the context.

B: Norms are not specifically tied to financial or ethical behavior alone.

C: Norms arise from social or organizational expectations, not exclusively regulations or standards.
