Question:
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
Solution:
Methane leads to both global warming \& 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.
