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 CO2{CO}_{2}
(D) Methane is a part of reducing smog

Choose the most appropriate answer from the options given below:

Options

  1. A(A),(B),(C)( A ) , ( B ) , ( C ) only
  2. B(A)( A ) and (B)( B ) only
  3. C(B),(C),(D)( B ) , ( C ) , ( D ) only
  4. D(A),(B),(D)( A ) , ( B ) , ( D ) only

Correct answer

A. (A),(B),(C)( A ) , ( B ) , ( C ) only

Step-by-step solution

Methane leads to both global warming & photochemical smog. Methane is generated in large amounts from paddy fields. CO2{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 CO2{CO}_{2}, Methane is not a component of reducing smog.
