Question

Freon is not recommended to be used in refrigerators because they:

• A. increase temperature
• B. deplete ozone
• C. affect environment
• D. affect human body

Answer 1

The correct option is B deplete ozone

Freon is basically a gas which is used for cooling. Chlorofluorocarbons or CFCs (also known as Freon) are non-toxic, non-flammable and non-carcinogenic. In the stratosphere the CFC molecules break down by the action of solar ultraviolet radiation and release their constituent chlorine atoms. These then react with the ozone molecules, resulting in the ozone layer depletion.

Hence the correct answer is option B.
