Which of the following factors relates to the participant requirements in a catering contract?

In a catering contract, participant requirements specifically focus on the details related to the number of guests and how their presence affects the service and pricing. The charge policy for additional participants is a crucial aspect because it defines how the caterer will handle situations where the number of attendees exceeds the original agreement. This includes determining any additional fees or adjustments in service levels, as well as the way the catering service will ensure that there are enough resources, such as food and seating, for all guests.

The presence of a charge policy allows both the caterer and the client to have clear expectations regarding financial responsibilities, especially if more guests than planned show up. This clarity protects both parties and helps in avoiding disputes over payment and service delivery.

Other factors, while important in their own right, do not directly address participant requirements. The floor plan for tables relates more to the logistics and arrangement of the event rather than how participants influence the catering agreement. Similarly, responsibility for insurance and gratuity policy involve different areas of contractual obligations and do not pertain specifically to managing participant counts or additional charges that may arise from them.
