Which statement is not true of ozone? a. it is a form of oxygen. b. it is an ingredient in smog. c. it produces ultraviolet radiation. d. it forms a layer in the upper atmosphere.

The correct answer is option (c). It produces ultraviolet radiations.

Explanation:

The ozone is a thin layer present in the stratosphere layer of  the atmosphere. Each molecule of ozone is made up of 3 oxygen atom. The ozone layer is mainly responsible for inhibiting the ultraviolet rays to enter in the earth's atmosphere. The ozone layer is not at all involved in the production of the ultraviolet rays. Hence, the statement ' it produces ultraviolet radiation' is incorrect about the ozone layer.
