D Correct answer
Explanation

Ozone (O3) in the stratosphere absorbs harmful ultraviolet radiation from the sun, acting as a protective shield for life on Earth. While ozone exists in the stratospheric layer, the question specifically asks about the substance that filters UV rays - ozone itself performs this function. The ozone layer absorbs UV-B and UV-C radiation, preventing it from reaching the surface.
