In meetings of a convention, what is the usual quorum requirement?

In the context of meetings, particularly within conventions, the quorum requirement typically refers to the minimum number of delegates required to be present in order to conduct business effectively. The correct choice reflects this principle, as it states that a majority of the registered delegates is necessary for a quorum.

Having a majority of the registered delegates ensures that decisions made during the meeting represent the will of the larger group, rather than just those who happen to be present at that moment. This requirement helps to maintain the integrity and legitimacy of the proceedings, as it ensures that sufficient representation exists to warrant action.

While other options suggest variations of a quorum based on presence or the chair's discretion, a majority of registered delegates is a commonly accepted standard in parliamentary procedure for larger assemblies. This ensures that decisions are made by a substantial portion of the body, rather than a simple majority of attendees or arbitrary numbers established by the leadership.
