- DAll of these
✓
Answer
Correct option: A.
Freon
a
The main cause of ozone depletion and the ozone hole is manufactured chemicals, especially manufactured halocarbon refrigerants, solvents, propellants and foam-blowing agents (chlorofluorocarbons Freon ,$(CFCs)$, $HCFCs$, halons), referred to as ozone-depleting substances $(ODS).$
