Hint: Depletion of ozone layer is mainly because of Chlorofluorocarbons. Chlorofluorocarbon (CFC) is made out of carbon, fluorine, and chlorine.
Complete answer:
Their business and modern worth in any case, CFCs were in the long run found to represent a genuine ecological danger. CFCs, once delivered into the air, aggregate in the stratosphere, where they add to the exhaustion of the ozone layer.
The primary driver of ozone consumption and the ozone gap is produced synthetics, particularly fabricated halocarbon refrigerants, solvents, charges, and froth blowing specialists (chlorofluorocarbons (CFCs), HCFCs, halons), referred to as ozone-draining substances (ODS). These mixes are shipped into the stratosphere by fierce blending in the wake of being radiated from the surface, blending a lot quicker than the particles can settle. Once in the stratosphere, they discharge halogen particles through photodissociation, which catalyze the breakdown of ozone $(O_3)$ into oxygen $(O_2)$.
Stratospheric ozone shields life on Earth from the destructive impacts of the Sun's bright radiation also called as UV radiations, even a generally little decline in the stratospheric ozone fixation can bring about an expanded rate of skin malignant growth in people and hereditary harm in numerous creatures.
Chlorofluorocarbons are utilized in refrigerators, air conditioners and vaporized splashes. They harm the ozone layer of the environment. Ozone layer exhaustion builds the measure of UVB that arrives at the Earth's surface. Research center and epidemiological investigations show that UVB causes non-melanoma skin disease and assumes a significant part in threatening melanoma improvement
Hence the correct answer is option ‘C’.
Note: At the point when CFCs contain hydrogen instead of at least one chlorine particle, they are called hydrochlorofluorocarbons, or HCFCs. CFCs are likewise called Freons.
