D. Switch

Answer :

Final answer:

Brian should use a buzzer to replace the device that converts electric energy into sound energy in the alarm clock.

Explanation:

The device that Brian should use to convert electric energy into sound energy is the buzzer.

A buzzer is an electronic device that produces a continuous or intermittent buzzing or beeping sound. When an electric current passes through the buzzer, it causes a small electromagnet to vibrate rapidly, which produces the sound waves that we hear as sound. This makes the buzzer a suitable choice for replacing the device in the alarm clock that converts electric energy into sound energy.
