Final answer:
The aircraft has a fuel injection system which offers better control over fuel delivery and improves fuel efficiency.
Step-by-step explanation:
The correct answer is D. Fuel injection system.
An aircraft typically has a fuel injection system. This system uses fuel injectors to spray fuel into the engine cylinders at precise intervals and in a fine mist. This allows for efficient combustion and optimal engine performance.
Unlike a carbureted fuel system, which mixes fuel with air before entering the engine, a fuel injection system delivers fuel directly into the engine cylinders. This provides better control over fuel delivery and improves overall fuel efficiency.
