Which of the following defines a quorum?

A quorum is defined as the minimum number of members required to be present at a meeting to legally conduct business. This concept ensures that decisions made during the meeting reflect the will of a sufficient segment of the group, preventing a small number of individuals from making decisions that impact all members. For various types of organizations, whether they are corporate boards, committees, or other assemblies, establishing a quorum is crucial for maintaining fair representation and effective governance.

While the other options refer to specific voting thresholds or requirements for decision-making—such as the number of votes needed to pass a measure, signatures for a contract, or the number of shareholders required to make company decisions—they do not specifically address the requirement for a certain number of members to be present for a meeting to take place. Thus, the definition correctly focuses on the presence of members rather than the actions or outcomes that follow.
