Correct Answer: Option D — variable or constant speed motor

The illustrated symbol represents a hydraulic motor. Unlike a pump, which converts mechanical energy into fluid power, a hydraulic motor converts fluid pressure and flow into rotary mechanical motion. These are frequently used for variable or constant speed applications in deck machinery and auxiliary equipment.
