Final answer:

A device using a motor is one that converts electrical energy into mechanical movement. An example of such a device would be an electric pump, as it uses an electric motor to move fluid.

Step-by-step explanation:

An electric motor transforms electrical energy into mechanical energy. Therefore, any device that converts electrical energy into mechanical movement incorporates a motor. From the options given, the correct answer is not explicitly mentioned; however, based on additional information provided for understanding, devices like an electric pump would use a motor. An electric pump transforms electrical energy into mechanical energy to move fluid, fitting the definition of a device using an electric motor. Additionally, it's important to note the distinction between types of engines and motors. For example, a heat engine converts thermal energy into mechanical energy and is different from an electric motor. A dynamo is another type of device that converts rotational energy, such as that generated by a water wheel or steam engine, into electrical energy, working in reverse compared to an electric motor.
