c)Distance from the source of sound
d)All of the above​

Answer 1

Explanation:

The loudness of sound is a phenomenon of a sound depending on the amplitude of the sound wave. If the amplitude of the sound wave is large, then the sound is said to be loud. The loudness of sound is directly proportional to the square of the amplitude of vibration and it is expressed in decibel (dB).

Answer 2

Option A (the amplitude of a sound wave) is the correct answer.
