    Answer: C-  The intensity increases by a factor 9

    Explanation: The intensity of a sound wave follows an inverse square law, that means that it is inversely proportional to the square of the distance: so  the new distance is the intensity will increase by a factor 9.

    My sentence- I hope that helped!
