What happens to a main motion after it has been laid on the table?

When a main motion is laid on the table, it remains within the control of the assembly, which is why the chosen answer is appropriate. Laying a motion on the table is a procedural action to temporarily suspend consideration of that motion, typically to allow the assembly to focus on more urgent matters. However, the motion can be taken from the table at a later time, allowing the assembly to resume discussion and ultimately decide on the motion.

This action does not remove the motion permanently; it is still part of the agenda and can be addressed again. As a result, the assembly retains control over the motion, choosing when or if to bring it back for further discussion or voting at a more appropriate time.

The other options describe situations that do not occur when a motion is laid on the table: it does not lead to permanent removal from consideration, the assembly maintains its control over the motion, and it certainly does not result in automatic adoption of the motion.
