_____ is the allotropic form of element ____ protects us from the harmful ultraviolet rays (UV rays) from the sun.
The correct option is A Ozone, oxygen
Ozone (O3) is the allotropic form of Oxygen(O2) that protects us from the harmful ultraviolet rays (UV rays) from the Sun. CFCs release highly reactive chlorine atoms into the atmosphere. These atoms damage the ozone layer, which leads to increased exposure to ultraviolet radiation and increased health risks. This is known as ozone layer depletion.
