CFC's or ChloroFluoroCarbons are emitted from fridges and A/C units.

Hope it helps :)

Answer 2

C.F.C is produced in this case.

• The C.F.C or chlorofluorocarbon is one of the most harmful gases which is produced from the human activities.
• The C.F.C is one of the root causes of the ongoing global warming.
• As mentioned earlier, the C.F.C is produced by human activities like the usage of air-conditioner and fridge. That's why, the correct answer to this question is C.F.C.
• The rest of the gases which are mentioned in the question, (ie. L.P.G , C.N.G , CO) are inappropriate in this context.
