Does a main motion require a second?

A main motion indeed requires a second to proceed further in formal meetings and discussions. The process of requiring a second ensures that there is sufficient interest in the motion being proposed. By having a second, it indicates that at least one other member supports the discussion of the motion, which helps to prevent frivolous or unworthy motions from wasting the time of the assembly. This procedural step is fundamental in parliamentary practice, as it promotes deliberative discussion and allows for a more organized debate on the proposed motion.

The other options do not align with parliamentary procedure, where the requirement for a second is a standard practice in most formal meetings to move a motion forward.
