The correct option is D ultraviolet-radiation

The ozone layer is a protective layer present in the stratosphere about 25 km from the surface of the earth.

UV radiations have many adverse effects on humans health and cause sunburn and skin cancer.

So, the correct answer is 'ultraviolet radiation'.
