• A. A- 2, B- 4, C- 1, D- 3
• B. A- 3, B- 4, C- 1, D- 2
• C. A- 1, B- 2, C- 3, D- 4
• D. A- 4, B- 2, C- 1, D- 3

Answer 1

The correct option is C A- 1, B- 2, C- 3, D- 4

Greenhouse gases are those that absorb and emit infrared radiation in the wavelength range emitted by earth. In order, the most abundant greenhouse gases in earth's atmosphere are: water vapour (H${}_{2}O$), carbon dioxide (CO${}_2$), methane (CH${}_4$), nitrous oxide (N${}_2$O), ozone (O${}_3$), chlorofluorocarbons (CFCs).

Therefore, the correct answer is option C.
