Answer 1

The correct option is A (i),(ii),(iii)

Ozone is a poisonous gas made up of three oxygen atoms. It is not stable near the Earth's surface. Ozone protects all the living organisms by absorbing harmful radiations from the Sun. CFCs are man-made compounds which react with the ozone molecules causing ozone depletion. This results in the formation of holes in the ozone layer.
