Question

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

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

Answer 1

The correct option is A 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 ${CO}_2$ which is produced due to deforestation and large scale combustion of fossil fuels. 'B' is the ${CH}_4$ which is produced by incomplete biomass combustion and is the major constituent of biogas. 'C' are the chlorofluorocarbons ${CFC}_s$ which are used as coolants in air conditioners and refrigerators.

So, the correct answer is 'A is the gas which is produced during the combustion of fossil fuels'.
