Fuel is normally supplied to an APU from the

APU independent fuel tank.
airplane`s header fuel tank.
airplane`s main fuel tank.
dedicated APU fuel line.

The correct answer is: airplane`s main fuel tank.

The APU (Auxiliary Power Unit) is a small gas turbine engine that provides power to essential systems in the airplane when the main engines are not running. The APU is usually supplied fuel from the airplane's main fuel tank, which is the largest fuel tank in the aircraft. APU fuel lines are connected to this main tank and provide fuel to the APU for efficient operation. Option A is incorrect because the APU does not have its own independent fuel tank. Option B is incorrect because the airplane's header fuel tank is used to supply fuel to the engine's fuel control system, not the APU. Option D is incorrect because the APU fuel line is connected to the main fuel tank, not a dedicated APU fuel line.
