Correct Answer - A
Ozone is found in the upper part of the atmosphere called stratosphere and it acts as a shield absorbing ultraviolet radiation from sun. So its depletion can lead to incidence of skin cancers caused by harmful solar radiations which will reach earth in the absence of `O_(3)` layer.
