The Food and Beverages department is one of the primary revenue-generating departments in a hotel, as it includes revenue from restaurants, bars, room service, and catering events.
- Laundry is a supporting service and typically does not generate significant revenue compared to food and beverage services.
- Security is another essential department but does not directly generate revenue for the hotel. Its main role is to ensure the safety of guests and property.
- Marketing supports revenue generation but does not directly generate income; it helps in promoting the hotel and attracting guests.
Thus, the correct answer is Food and Beverages.
