Choose the correct answer from the options given below:

1. C, A, B, D
2. A, C, B, D

4. A, C, D, B

Answer 1

Correct Answer - Option 1 : C, A, B, D

Carbon dioxide (CO2) makes up the vast majority of greenhouse gas emissions from the sector, but smaller amounts of methane (CH4) and nitrous oxide (N2O) are also emitted. These gases are released during the combustion of fossil fuels, such as coal, oil, and natural gas, to produce electricity.

According to World Green House Gas Emission Data, the correct sequence of countries in decreasing order of their contribution to global carbon dioxide emissions is China, USA,  EU - 28, India, Russia, Japan.

Country	CO2 Emission (billion metric ton)	Global share
China	9.43	27.8%
USA	5.15	15.2%
EU - 28	3.59	10.6%
India	2.48	7.3%
Russia	1.55	4.6%
Japan	1.15	3.4%

Therefore, option 1 is the right answer.
