No, The write answer is D
Limiting vehicle speed is only possible if we maintain the engine speed constantly. So Option D is the prime cause.
Maintain engine speed
IT is a mechanical device which is used maintain constant speed with variations of load
I think it should be option (D) To maintain the engine speed
Limit the vehicle speed
