Answer 1

 It is inversely proportional to the square of the distance of the listener from the source 
so B is the right option 
hope this helps

Answer 2

Answer:

B. It is inversely proportional to the square of the distance of the listener from the source.

Explanation:

The loudness of sound is determined by the intensity of the sound waves. The intensity of the sound is inversely proportional to the area of ​​the wavefront, which in this case is proportional to the square of the distance to the source. Therefore, the loudness is inversely proportional to the square of the distance of the listener from the source.
