Question

Observe the following statements
Statement-I: The carbon containing components of photochemical smog are acrolein, methanal and PAN
Statement-II: The number of greenhouse gases in the list given below is 5
$\text{CH}_4, \text{CO}_2, \text{NO}, \text{H}_2\text{O}(\text{l}), \text{H}_2\text{O}(\text{g}), \text{O}_2, \text{O}_3$
The correct answer is

• A. Both statements I and II are correct
• B. Both statements I and II are not correct
• C. Statement I is correct, but statement II is not correct
• D. Statement I is not correct, but statement II is correct

Hint:

Photochemical smog involves a mix of primary and secondary pollutants. The major GHGs are water vapor ($\text{H}_2\text{O}$), carbon dioxide ($\text{CO}_2$), methane ($\text{CH}_4$), nitrous oxide ($\text{N}_2\text{O}$), and ozone ($\text{O}_3$). Diatomic gases of the same element, like $\text{O}_2$ and $\text{N}_2$, are not greenhouse gases.
