What is the correct increasing order of the Global Warming Potential (GWP) of the following gases? Choose the correct answer from the options given below.

1.Nitrous Oxide (N2O)

2.Carbon dioxide (CO2)

3.Chlorofluorocarbon (CFC)

A1, 2, 3

B1, 3, 2

C2, 1, 3 ✓ Correct

D2, 3, 1

Correct answer: (C) 2, 1, 3

Explanation

GWP rises from Carbon dioxide to Nitrous oxide to Chlorofluorocarbon, giving 2, 1, 3.

Carbon dioxide is the reference gas with a GWP of one.

Nitrous oxide traps far more heat per molecule, with GWP in the hundreds.

Chlorofluorocarbons are the strongest here, with GWP in the thousands.

Ordering them low to high gives CO2, N2O, CFC.
