Answer

Brief Explanations:

A motor converts electrical energy into mechanical energy. A body - massager uses electric energy to move back and forth, which is the function of a motor. A water - heater converts electrical energy to heat energy, a waterfall turning a water - wheel is a form of mechanical energy transfer without an electric motor, and a solar charger converts solar energy to electrical energy.

Answer:

C. A body massager uses electric energy to move back and forth.
