Question

with very few exceptions, a member never speaks:
o longer than five minutes.
o more than once on a main notion.
o unless permission is granted by the make of the motion.
o while seated.

Explanation:

In many formal group - discussion settings, a common rule is that members usually don't speak for more than five minutes to keep the discussion flowing and inclusive. Speaking more than once on a main notion is also often restricted to give others a chance to contribute. Speaking while seated is not a universal taboo and permission from the motion - maker is not a typical general restriction on speaking.

Answer:

A. longer than five minutes.
