Who generally attends a convention?

A convention is typically organized for a specific group, often associated with particular interests or political goals. Delegates are chosen representatives who attend the convention to discuss, propose, and vote on various matters relevant to the convention’s purpose. These delegates may be elected or appointed from a larger body or constituency, reflecting the views or decisions of those they represent.

In contrast, the other groups listed, such as the public at large or only registered voters, do not typically have the same level of organized representation as delegates. The organizing committee, while vital for planning and executing the convention, does not encompass all the varied voices and perspectives that delegates represent from their respective groups. Thus, the attendance of delegates, who engage in discussions and decision-making processes, stands as the primary focus of a convention, making this the correct answer.
