Best Answer Explained in Below-:

The ozone layer, located in the stratosphere, plays a crucial role in protecting life on Earth by absorbing the majority of the Sun's harmful ultraviolet (UV) radiation. This layer is composed primarily of ozone (O3) molecules, which efficiently absorb UV radiation in the wavelengths that can cause skin cancer, cataracts, and other health problems in humans, as well as damaging ecosystems and wildlife.

Among the options provided, ultraviolet radiation is particularly harmful due to its ability to alter DNA and biological processes. The other types of radiation mentioned—infrared radiation, visible light, and gamma rays—interact with matter in different ways. Infrared radiation is primarily experienced as heat and is not significantly absorbed by ozone. Visible light is necessary for photosynthesis and is not restricted by the ozone layer. Gamma rays, while highly energetic, are largely absorbed by the Earth's atmosphere as a whole rather than specifically by the ozone layer. Therefore, the correct answer is A) Ultraviolet radiation, as it directly pertains to the protective function offered by the ozone layer in shielding the planet from its detrimental effects.
