Explanation:

Statement 1: CFC is a manmade gas, and so all options containing CFC will be wrong.

Statement 2: Methane is emitted by rice field, animals (digestive tracts), coal mines etc.

Statement 3: Nitrous oxide (N2O) is produced by fertilizer use, animal waste management, fossil fuel combustion, industrial activities, soils under natural vegetation and the oceans. So, it is produced by both natural and human activities. 3 will still be correct.

Statement 4: SF6 is an inorganic extremely potent greenhouse gas, which is an excellent electrical insulator. It is a manmade gas.

Statement 5: Oxygen (O2) is not a GHG, ozone (O3) is.

Statement 6: Water vapour is a very important GHG, and it is obviously natural.
