None of the above

Detailed explanation-1: -The ozone layer in the stratosphere absorbs a portion of the radiation from the sun, preventing it from reaching the planet’s surface. Most importantly, it absorbs the portion of UV light called UVB. UVB is a kind of ultraviolet light from the sun (and sun lamps) that has several harmful effects.
Detailed explanation-2: -In particular, the ozone layer protects us from the UV radiation, known as UV-B, which causes sunburn. Long-term exposure to high levels of UV-B threatens human health and damages most animals, plants and microbes, so the ozone layer protects all life on Earth.
Detailed explanation-3: -It absorbs all the ultraviolet radiations and does not allow them to reach earth’s surface, thus protecting all living organisms from the harmful effects of UV radiations. The ozone layer absorbs the radiation and maintains the natural cycle of oxygen and ozone.
Detailed explanation-4: -The importance of ozone is defined by the fact that it protects the earth from harmful ultraviolet rays from the sun. The ozone layer is found in the upper regions of the stratosphere where it protects the earth from the harmful ultraviolet rays of the sun. These radiations can cause skin cancer in humans.
Detailed explanation-5: -The stratospheric ozone layer is Earth’s “sunscreen” – protecting living things from too much ultraviolet radiation from the sun.
