Vedclass · Answer

(A) The relative contribution of various greenhouse gases to global warming is as follows:$1$. Carbon dioxide $(CO_2)$: $60\%$$2$. Methane $(CH_4)$: $20\%$$3$. Chlorofluorocarbons $(CFCs)$: $14\%$$4$. Nitrous oxide $(N_2O)$: $6\%$Comparing these values with the given options, option A correctly represents the proportions: $60\%\ CO_2, 20\%\ 	ext{Methane}, 14\%\ CFCs, 6\%\ N_2O$ is the standard NCERT data. Since the provided options contain errors in matching the standard data, we identify the closest logical structure or correct the sequence.

Choose the correct option for the proportion of various greenhouse gases contributing to global warming.
