Examples of devices that convert electrical energy into mechanical energy — in other words, devices that use electrical energy to move something — include:
the motor in today’s standard power drills
the motor in today’s standard power saws
the motor in an electric tooth brushes
the engine of an electric car
the motor in a fan
the motor in a remote control cars that runs on batteries. So your answer would be B. Motorsport
