Which of the following is one of the four parts of an aircraft as listed?

• A. Engine
• B. Wings
• C. Fuselage
• D. Horizontal Stabilizer

Answer: (C)

The main idea here is recognizing a primary airframe section—the fuselage. The fuselage is the aircraft’s main body, where the crew sit, passengers travel, and cargo is carried; it connects the wings, tail, and propulsion system into a single structure.

The engine is a propulsion component that provides thrust, the wings generate lift to keep the aircraft aloft, and the horizontal stabilizer adds stability and controls pitch at the tail. While all of these are essential parts, the fuselage stands out as the central body that houses people and payload and ties the other systems together, which is why it’s the best choice among the listed options.
