A proposal to be acted upon by a group is known as a:

A motion is a formal proposal put forward for discussion and decision-making within a group setting, such as a board meeting or legislative body. It serves as the means by which members can propose new ideas, changes, or actions that they believe should be considered by the group. The process typically involves a member stating the motion, followed by a seconding from another member to indicate support for its consideration. Once a motion is on the floor, the group can debate its merits, make amendments, and ultimately vote on it.

In contrast, a resolution refers specifically to a formal expression of opinion or intention agreed upon by a group, often following a motion. A statement is a broad term that could refer to any communicative expression and does not necessarily imply a proposal for group action. A proposal is a general term that can imply suggesting an idea but lacks the procedural context that a motion carries within formal meetings. Thus, understanding the specific function of a motion within organizational processes highlights why it is recognized as the correct answer.
