Answer:

public

Brief Explanations:

The free - rider problem occurs when individuals benefit from a collective good without contributing. Public interest groups advocate for collective goods (e.g., environmental protection, civil rights) that benefit everyone. Since these goods are non - excludable (hard to stop non - contributors from enjoying them), people may be less motivated to contribute, making public interest groups more vulnerable to the free - rider problem. Economic interest groups (e.g., labor unions, business associations) often offer selective incentives (e.g., job benefits, industry - specific services) to members, reducing free - riding. Government entities are not interest groups in the traditional sense of advocacy. Equal - opportunity groups, while advocating for rights, may not face the same scale of non - excludable collective goods as public interest groups.
