Question

Given pie-diagram represents the relative contribution of various GHGs to total global warming. Select the correct statements(s) regarding A, B and C -

• A. B are the chemicals which are used as coolants in refrigerators
• B. A is the gas which is produced during the combustion of fossil fuels
• C. All of these
• D. C is the gas which is the major constituent of biogas

Answer 1

The correct option is B A is the gas which is produced during the combustion of fossil fuels

In the given pie diagram, relative contribution of various greenhouse gases are shown.

'A' is the $C{O}_2$ ​ which is produced due to deforestation and large scale combustion of fossil fuels.

'B' is the $C{H}_4$ which is produced by incomplete biomass combustion and is the major constituent of biogas.

'C' are the chlorofluorocarbons CFCs which are used as coolants in air conditioners and refrigerators.

So, the correct answer is "option A"
