Correct option is C
The ozone layer in the stratosphere acts as a shield that absorbs and filters out the sun's harmful ultraviolet (UV) radiation, particularly UV-B rays. When the ozone layer is depleted, more UV-B radiation reaches the Earth's surface. Increased exposure to UV-B radiation is known to cause skin damage, leading to a higher risk of skin cancers, such as melanoma and basal cell carcinoma.
