The satements that are TRUE :
(A) Methane leads to both global warming and photochemical smog
(B) Methane is generated from paddy fields
(C) Methane is a stronger global warming gas than $\mathrm{CO}_{2}$
(D) Methane is a part of reducing smog Choose the most appropriate answer from the options given below :
Correct Option: 1
Methane leads to both global warming $\backslash$ \& photochemical smog. Methane is generated in large amounts from paddy fields. $\mathrm{CO}_{2}$ can be absorbed by photosynthesis, or by formation of acid rain etc., while no such activities are there for methane. Hence methane is stronger global warming gas than $\mathrm{CH}_{4}$. Methane is not a part of reducing smog.
