Which of the following is NOT one of the responsibilities of an event planner?

The correct choice highlights that leading marketing campaigns is not typically a direct responsibility of an event planner. Event planners primarily focus on the logistical aspects of organizing an event, which includes budgeting to ensure the event stays financially viable, acquiring permits to comply with legal and local regulations, and planning food to meet the dietary needs and tastes of attendees.

While marketing may play a role in promoting an event, it is often managed by a separate marketing team or individual who specializes in that area. An event planner's expertise lies in coordinating every detail of the event—from the venue selection to the timeline—rather than executing the promotional strategies necessary to attract participants. Therefore, the role typically does not encompass the comprehensive responsibilities associated with leading marketing campaigns.
