\nThe correct answer is A) ultraviolet-A and ultraviolet-B radiations.
\n<\/section>\n
\nOzone (O\u2083) in the stratosphere forms the ozone layer, which is crucial for life on Earth because it absorbs a significant portion of the sun’s harmful ultraviolet (UV) radiation before it reaches the surface. While ozone is most effective at absorbing UV-B radiation (wavelengths 280-315 nm), which is particularly harmful to living organisms, it also absorbs a considerable amount of UV-A radiation (315-400 nm) and virtually all UV-C radiation (100-280 nm).
\n<\/section>\n
\nUV-A radiation is less harmful than UV-B but can still cause skin damage and premature aging. UV-B radiation is the primary cause of sunburn, skin cancer, and cataracts. UV-C radiation is the most energetic and harmful but is completely absorbed by the ozone layer and oxygen in the atmosphere. Therefore, the presence of stratospheric ozone is important for absorbing both UV-A and UV-B, reducing their intensity at the Earth’s surface.
