Solution

The correct option is C $I n t e n s i t y α (A m p l i t u d e)^{2}$
Intensity is a measure of loudness of sound. Intensity is defined as the amount of energy passing per unit area per unit time in a direction normal to the area. Intensity of sound is directly proportional to the square of amplitude of sound.
