Which term refers to the interior area of an aircraft that houses passenger seating?

• A. Bulkhead
• B. Bidding
• C. CABIN
• D. APU

Answer: (C)

The term for the interior area where passengers sit is the cabin. In aviation, the cabin is the enclosed passenger compartment that contains seating, aisles, overhead bins, galleys, and lavatories. A bulkhead is a wall that separates sections inside the aircraft, not the seating area itself. An APU, or auxiliary power unit, is a power source located in the tail of the plane and unrelated to where passengers sit. Bidding refers to seat assignment or scheduling processes and doesn’t describe the interior space either. So, the cabin is the correct term.
