Which of the following is not a method for the production of ozone?
Electrolysis of water
Ultraviolet radiation of oxygen
Combustion of fossil fuels
Corona discharge
The combustion of fossil fuels does not produce ozone. Ozone can be produced through the electrolysis of water, ultraviolet radiation of oxygen, and corona discharge, which involves passing oxygen through an electrical field. Hence option C is the correct answer.
Option (A) is incorrect because electrolysis of water produces ozone. Hence option A is incorrect.
Option (B) is incorrect because Ultraviolet radiation of oxygen produces ozone. Hence option B is incorrect.
Option (D) is incorrect because Corona discharge produces ozone. Hence option D is incorrect.
