The correct option is C CO2 and N2O
Green-house gases absorbs the infrared radiation emitted by earth's surface and heated the atmosphere is the green-house effect. In order, the most abundant green-house gases in Earth's atmosphere are water vapor (H2O), carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), ozone (O3), chlorofluorocarbons (CFCs). Thus, the correct answer is option C.
