The correct answer is:
D. doesn't require a quorum.
A quorum is the smallest number of people needed to be present at a meeting before it can officially begin and before official decisions can be taken. A committee of the whole is a device in which a legislative body or other deliberative assembly sits as a single committee with all assembly members being committee members. Most House business is conducted within the Committee of the Whole because this arrangement doesn't require a quorum.
