CABIN is the interior of the aircraft containing passenger seats.

• A. The cockpit.
• B. The interior of the aircraft containing passenger seats.
• C. The cargo hold.
• D. The wing.

Answer: (B)

CABIN refers to the passenger compartment inside the aircraft—the interior where seats, aisles, and passenger amenities are located. This space is distinct from the cockpit, which is the flight deck used by pilots; from the cargo hold, which lives beneath the cabin and stores baggage and freight; and from the wing, which is part of the aircraft’s structure outside the cabin. So the statement that CABIN is the interior of the aircraft containing passenger seats is correct because it designates the area designed for travelers and their seating.
