The ozone layer mainly protects the Earth from what?
The governing scientific concept is the protective role of atmospheric ozone. Ozone molecules in the stratosphere absorb much of the Sun’s harmful ultraviolet radiation, especially UV-B and nearly all UV-C, thereby reducing damage to living cells. Infrared radiation is associated mainly with heat, visible light enables vision, and radio waves are not the primary radiation blocked by ozone. Hence, option A is correct.
