A1, 2, 3 only
B1, 4 only
C2, 4, 5 only
D2, 3, 5 only ✓ Correct
Correct answer: (D) 2, 3, 5 only — NO, NO2 and CO cause indirect greenhouse warming, so the answer is 2, 3 and 5.
Explanation
★NO, NO2 and CO cause indirect greenhouse warming, so the answer is 2, 3 and 5.
★These gases are not strong greenhouse gases themselves.
★They affect the concentrations of other greenhouse gases like ozone and methane.
★So their warming effect is indirect.
★CH4 and N2O are direct greenhouse gases, not indirect ones.
★Hence 2, 3 and 5 is correct.
