The "poor" and the homeless are two examples of

A) public interest groups.
B) potential interest groups.
C) citizen interest groups.
D) grassroots interest groups.

The "poor" and the homeless are potential interest groups because they have a common interest or goal but may not be organized or actively advocating for their interests. Public interest groups are organizations that pursue goals that benefit society as a whole rather than just a particular group. Citizen interest groups are organized around a specific issue or concern, while grassroots interest groups are composed of individuals who come together to advocate for specific issues or causes at the local level.
