Correct Answer:
B. One half members
The concept of a quorum is fundamental to the legitimacy of any meeting, ensuring that a sufficient number of members are present to make valid decisions. For a meeting of the Authority, the quorum is typically set at One half members. This ensures that a significant portion of the body is present, reflecting a broad consensus and preventing decisions from being made by a small, unrepresentative minority. Options like 'One third members' or 'One fourth members' would allow too few members to make critical decisions, potentially undermining the authority's mandate. Conversely, 'Two third members' might make it excessively difficult to convene meetings regularly, hindering operational efficiency.
