The numeral in the rule for the notice period before a meeting is:

The correct answer is 3. The notice period before a meeting is a fundamental aspect of procedural fairness and proper governance. This foundational concept ensures that all participants have adequate time to prepare, review materials, and arrange their schedules.

• 3 is accurate because it specifies the required duration for advance notification before a meeting, as stipulated by the rules. This ensures proper communication and preparation.
• 1, 2, and 5 are false as they do not match the stipulated notice period. Providing insufficient or excessive notice could lead to procedural irregularities, lack of participation, or inefficiencies.
