Correct option is C
Major Greenhouse Gases:
Greenhouse gases trap heat in the Earth's atmosphere, contributing to global warming and climate change. The
major greenhouse gases include:
1.
Carbon dioxide (CO₂): Released through burning fossil fuels, deforestation, and industrial processes.
2.
Methane (CH₄): Emitted from livestock, landfills, and oil and gas extraction. It is more potent than CO₂ in trapping heat.
3.
Nitrous oxide (N₂O): Released from agricultural activities (e.g., use of fertilizers) and burning of fuels.
Carbon Monoxide (CO):
· Carbon monoxide is
not a major greenhouse gas.
· It is a toxic gas emitted from incomplete combustion of carbon-containing fuels (e.g., car exhaust, fires).
· Although harmful to human health, it does not significantly contribute to the greenhouse effect.
