D Correct answer
Explanation

The ozone layer in the stratosphere absorbs most of the sun's ultraviolet (UV) radiation, especially UV-B and some UV-C rays. This prevents harmful UV from reaching Earth's surface where it would damage living organisms, causing skin cancer and other harm. Visible light and infrared radiation pass through the atmosphere largely unaffected.
