Answer: Answer is d (Filters out harmful UV radiation)
Step-by-step explanation:
The ozone layer is present in the second layer of the atmosphere which is known as the Stratosphere. In this layer ozone filters out the ultraviolet radiation from the sun's rays before entering the earth's surface. UV rays cause harmful effects on human life such as sunburn, premature aging, and skin cancer.
But the depletion of the ozone layer due to greenhouse gases is leading to an increase in ground-level ultraviolet radiation because it is an effective absorber of UV rays.
