the answer is =

(D).......

Answer 2

(D) Assertion and reasons are both correct, but the reason is not the correct explanation for the assertion.

- Ozone (O3) gas is present in the upper stratosphere.

- When CFCs react with ozone, then it breaks the molecule of ozone gas which results in ozone layer depletion.

- Ozone layer protect us from harmful ultraviolet (UV) radiations coming from the sun.

- Thus, ozone holes increase the amount of UV radiation reaching the earth.

- Hence, assertion and reason both are correct, but the reason is not the explanation for the assertion.
