Answer:

b. use of chlorofluorocarbons (CFCs).

Ozone layer act as a shield that is found in the stratosphere layer of the Earth.It envelopes the entire planet and protects the planet and the organism from the harmful Ultraviolet radiation (UV-B) from the sun.

  • The ozone layer is made up of three oxygen atoms.

  • The ozone plays a vital role as it protects from radiation which can cause skin cancers, eye problems, and breathing problems.

The correct option is :

Option B. use chlorofluorocarbons (CFC's).

  • The control of depletion of the ozone layer is very necessary and can be done by limiting the use of halocarbon refrigerants, propellants, CFCs, HCFCs.

  • Chlorine and bromine from these chemicals destroy the ozone layer by interacting with the oxygen molecule of the ozone.

Therefore, the depletion of ozone can be controlled by reducing the use of chlorofluorocarbons (CFCs).
