Question

Sulphur oxides which are responsible for major air pollution are caused by:

• A. burning of coal and refining of pertoleum
• B. burning of fuels in automobiles
• C. combustion of fuels containing C and H
• D. using indoor combustion devices like cooking gas.

Answer 1

The correct option is A burning of coal and refining of pertoleum

$S{O}_2$ is a major gaseous pollutant found in the lower atmosphere. They are the compounds of sulphur and oxygen molecules. So when the fuels such as coal and oil are burnt, it leads to emission of $S{O}_2$ gas.
