In a hotel, the Rooms Division is the department that directly generates revenue by selling rooms to guests. This division includes the front desk, reservations, and housekeeping, which are critical in generating income from guest stays.
- Human Resources handles staffing and employee welfare, but it does not directly generate revenue.
- Security ensures the safety of guests and property but does not directly generate income.
- Engineering is responsible for maintaining the hotel's infrastructure but does not directly generate revenue either.
Thus, the correct answer is Rooms Division.
