The major problem with CFCs is that It is a greenhouse gas, Option A is correct.

Chlorofluorocarbons (CFCs) are nontoxic, nonflammable chemicals containing atoms of carbon, chlorine, and fluorine.

They are used in the manufacture of aerosol sprays, blowing agents for foams and packing materials, as solvents, and as refrigerants.

CFCs are classified as halocarbons, a class of compounds that contain atoms of carbon and halogen atoms

The major problem with CFC's is that they are green house gases

It destroys ozone in the upper atmosphere (stratosphere).

CFCs can produce more than 10,000 times as much warming, pound for pound, once they are in the air.

It is not only because of their dramatic warming potential but also

They were found to be the primary cause of the rapidly escalating destruction of the Earth’s ozone layer,

which protects the planet from dangerous, cancer-causing levels of ultraviolet radiation.

Therefore The major problem with CFCs is that It is a greenhouse gas, Option A is correct.
