What are the two categories of committees as identified in parliamentary procedure?

Committees play a vital role in the structure of parliamentary procedure by facilitating the organization and management of tasks within an assembly. The correct categorization of committees is into standing and special committees.

Standing committees are permanent and are established to focus on specific areas of ongoing concern within the assembly, such as finance, membership, or rules. They are typically formed at the beginning of an organizational year and continue from session to session, providing continuity and expertise in their designated areas.

Special committees, on the other hand, are temporary and convened for a specific purpose, such as investigating a particular issue or planning a special event. Once their assigned task is complete, these committees are disbanded. This temporary nature allows flexibility for the organization to address specific needs without the commitment of a standing committee.

The other options do not accurately reflect the established categories recognized in parliamentary procedure. Advisory and executive committees often describe the roles played by committees but do not encompass the structural categorization. Mandatory and optional or formal and informal does not align with the standard terminology used in parliamentary systems. Therefore, standing and special are indeed the appropriate classifications for committees within parliamentary procedure.
