Question

Gases referred to as 'green house gases' are

• A. CO${}_2$, O${}_2$, NO${}_2$, NH${}_3$
• B. Chlorofluoro carbon, CO${}_2$, NH${}_3$, N${}_2$
• C. CH${}_4$, N${}_2$, CO${}_2$, NH${}_3$
• D. Chlorofluoro carbon, CO${}_2$, CH${}_4$, NO${}_2$

Answer 1

The correct option is D Chlorofluoro carbon, CO${}_2$, CH${}_4$, NO${}_2$

The concentration of oxides increases due to the high rate of emission from the vehicle and other human activities like deforestation. The oxides form a layer which traps solar radiation to escape the earth atmosphere which leads to global warming.

So, the correct answer is option D.
