Answer

Brief Explanations:

Sound energy and loudness are related to the amplitude of a sound - wave. Larger amplitudes mean more energy and greater loudness. Amplifiers work by increasing the amplitude of the sound - wave. Rarefaction is part of the wave structure related to pressure, speed affects how fast the wave travels, and wavelength is related to frequency, not directly to energy and loudness in the way amplitude is.

Answer:

A. amplitude
