(b) Ozone can oxidise sulphur dioxide present
in the atmosphere to sulphur trioxide.
(c) Ozone hole is thinning of ozone layer
present in stratosphere.
(d) Ozone is produced in upper stratosphere
by the action of UV rays on oxygen.

Answer 1

(b) is the answer.....

Answer 2

(a) Ozone is not responsible for green house effect.

Explanation:

The ozone layer or ozonosphere contains relatively high concentrations of ozone (O3) molecules. The ozone layer protects us from the harmful effects of the ultraviolet radiations of the sun by blocking these UV rays. Without the ozone layer, these UV rays would reach the Earth's surface and cause injury and may even kill most living things. The thinning of ozone layer of stratosphere at some places is called ozone depletion. Ozone is responsible for green house effect. So statement A is incorrect.

Option A is the answer.
