D. The intensity increases to by a factor of 16.
SUBMIT

The intensity decreases by a factor of 4.

Explanation:Now the inverse square law is applied; the intensity of a sound varies inversely with the square of the distance from the source of the sound. a. As the distance is doubled (4 m is two times 2 m), the intensity level is reduced by a factor of 4.

the answer is b. dilution
