Solution

The correct option is C
CFCs-14%, Methane-20%

The most abundant greenhouse gas in the atmosphere is carbon dioxide, followed by methane, nitrous oxide and then CFCs. Oxygen is not a greenhouse gas. Carbon monoxide is a very weak greenhouse gas, but has quite a few indirect effects on global warming.
