Solution

The correct option is A
Amplitude

Loudness determines the magnitude of the auditory sensation produced. More the intensity of sound wave, more is the loudness. Intensity of the sound wave depends on the energy per unit volume in the wave. Energy itself is proportional to the (square of) amplitude of the wave.
