Answer: The correct answer is (d).

Explanation:

The stereo has a dial that changes the volume of the sound the stereo makes.

The intensity of the sound increases with the amplitude of the sound wave. The energy of the sound wave is directly proportional to the amplitude of the wave.

The loudness of the sound increases with increase in the amplitude of the sound wave.

Therefore, the stereo has a dial that changes the volume of the sound the stereo makes. In this case, the dial is changing the amplitude of the sound waves.
