Answer 1

The correct option is D Ozone in upper part of atmosphere is harmful to animals.

$\text{Ozone}$

A layer of ozone is present in the upper part of the atmosphere (stratosphere) acting as an umbrella to prevent the harmful UV radiations from reaching Earth’s surface.

Ozone present in the troposphere (lower atmosphere) is a pollutant and extremely harmful. It is called 'Bad Ozone'.

Hence, the given statement in option (a) is incorrect.
