D None of the above

Show answer and explanation

Answer: B. Amplitude increases loudness of a sound

Loudness is directly related to the energy of a sound wave. The more energy a vibration has, the larger the wave's amplitude (its height), and the louder the sound will be.
Amplitude: This measures the strength or "size" of the vibration. If you pluck a guitar string harder, you increase its amplitude, making the sound louder.
