B) Sets a guided focus for the meeting

Explanation:

Setting a meeting agenda is important for you to select all the important points that should be discussed. This is to optimize the meeting and prevent secondary issues from taking up meeting time. When you organize the points, you can better manage the time for each topic to be discussed in proportion to its relevance.
