Which motion cannot be debated or amended during the meeting?

The motion that cannot be debated or amended during a meeting is known as a privileged motion, which includes motions like the Previous Question. This specific motion serves to end discussions on a matter immediately and move directly to a vote. The rationale behind not allowing debate or amendment on this motion is to maintain the efficiency and order of the meeting, ensuring that discussions do not become prolonged unnecessarily.

In parliamentary procedure, certain motions, particularly those aimed at maintaining the flow of the meeting, have restrictions on debate and amendment. Previous Question is designed to allow members to determine when they wish to conclude debate and make a decision on the pending question, reinforcing the importance of time management and decisive action during meetings.

The other choices relate to actions that influence the progression and handling of matters being considered but do allow for discussion or modification before a final decision is made. Thus, it's the nature and intent of the Previous Question that solidifies it as the correct answer here.
