Justification: 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.

Natural Greenhouse Gases
1. Methane
Methane is a potent greenhouse gas that is produced through both natural and human activities. It is released during the production and transport of coal, oil, and natural gas. However, it is also emitted by natural processes such as the decay of organic matter in wetlands, the digestive processes of certain animals, and the natural seepage of methane from geological formations.
2. Nitrous Oxide
Nitrous oxide is another greenhouse gas that occurs naturally in the atmosphere. It is produced by natural processes such as microbial activity in soils and oceans, as well as by the combustion of fossil fuels and solid waste.
3. Water Vapor
Water vapor is the most abundant greenhouse gas in the atmosphere and is primarily generated through natural processes such as evaporation from oceans, lakes, and rivers. It also plays a crucial role in the Earth's climate system, as it acts as a feedback mechanism, amplifying the effects of other greenhouse gases.
Greenhouse Gases Not Present in the Atmosphere due to Natural Activities
1. Chlorofluorocarbons
Chlorofluorocarbons (CFCs) are synthetic compounds that were primarily used as refrigerants, propellants, and solvents. They are not naturally occurring in the atmosphere and are entirely human-made. CFCs have been phased out due to their destructive effects on the ozone layer.
2. Sulfur Hexafluoride
Sulfur hexafluoride (SF6) is a synthetic gas that is used in various industries for tasks such as electrical insulation and as a tracer gas for leak detection. Similar to CFCs, SF6 is not naturally occurring and is solely a product of human activities.
Conclusion
In conclusion, the natural greenhouse gases present in the atmosphere are methane, nitrous oxide, and water vapor. These gases are released through natural processes such as microbial activity, evaporation, and the decay of organic matter. On the other hand, chlorofluorocarbons and sulfur hexafluoride are entirely human-made gases and are not naturally occurring in the atmosphere.
