Explanation:

The correct option is an appointment does not require coworkers, but a meeting includes coworkers

A meeting differs from an appointment mainly because an appointment is an schedule that has an effect only on a personal calendar while a meeting is a schedule that can involve the attendance of one or more other people who will be invited and indicate readiness to attend.
