Answer 1

The correct answer is Sulfur hexafluoride (SF6).

Global warming refers to the rise in global temperatures due to the increasing concentrations of greenhouse gases in the atmosphere.
Increased levels of CO₂ can lead to the warming of the earth's atmosphere and thereby can lead to global warming
The ultimate objective of the United Nations Framework Convention is to stabilize greenhouse gas concentrations "at a level that would prevent dangerous anthropogenic (human-induced) interference with the climate system.
The global warming potential of Sulfur hexafluoride (SF6) is the highest among all the given gases.
Carbon dioxide (CO2) is the least global warming potential gas.
Nitrous oxide (N2O) has a higher Global Warming Potential compared to Methane (CH4).
