What type of motion is categorized as 'Privileged Motions'?

Privileged motions are special types of motions that have precedence over other motions and are typically concerned with the rights and privileges of the assembly or its members. The motion to "Raise a Question of Privilege" is specifically categorized as a privileged motion because it allows a member to raise an urgent issue that affects their rights or the welfare of the assembly. For instance, if a member feels that their ability to participate effectively is being hindered, they may invoke this motion to address that concern immediately.

The other choices listed are not privileged motions; they involve procedural treatments of the main motion rather than addressing immediate rights or conditions within the meeting. "Postpone Indefinitely," "Refer to a Committee," and "Amend a Motion" are all classified under regular or subsidiary motions, which are used to handle the discussion of the main motion rather than addressing urgent issues directly affecting the assembly's proceedings.
