Final answer:
A member proposing a main motion typically has the right to offer a brief explanation, but detailed reasons and debate usually take place after the motion is proposed and seconded.
Step-by-step explanation:
Before proposing a main motion, a member of a parliamentary body or committee usually has the right to B. offer an explanation for the motion. This explanation provides a reason or rationale for why the motion is being proposed, which can assist other members in understanding the purpose of the motion and how they might want to vote on it. While the member may provide some details, they do not need to C. explain all the reasons in detail for making the motion at this stage, nor D. debate the motion yet. The full debate usually takes place after the motion has been proposed and seconded.
