The correct answer is B.
American citizens may belong to any number of interest groups at one time.
There is no rule about the number of interest groups one can belong to.
An interest group is an organization of people who share a common interest and work together to promote their goals by means of influencing the government.
The interest groups are usually divided into two groups: economic and noneconomic.
Economic groups seek some kind of economic advantage for their members.
Noneconomic groups are interests groups that fight for causes rather than material gains.
