Which of the following motions pertains to the order of business in a meeting?

The motion that pertains to the order of business in a meeting is the point of order. A point of order is raised when a member believes that the rules of the meeting, whether they be parliamentary procedure or the organization's standing rules, are not being followed. This motion helps ensure that the meeting proceeds according to established guidelines and order.

When a point of order is called, it typically requires the chair to respond and provide a ruling on the matter, thus maintaining the integrity of the meeting's structure. This motion directly addresses procedural issues and is essential for ensuring that the meeting adheres to its agenda and is conducted fairly and efficiently.

The other options focus on different aspects of meeting procedures. For instance, limiting or extending debate pertains to how long members can discuss a motion, while withdrawing or modifying a motion refers to the ability of the proposer to alter the motion that has been presented. Ending debate involves bringing discussions on a motion to a close, but none of these directly address the overarching order of business like a point of order does.
