Assertion : Suspended particulate matter (SPM) is an important pollutant released by diesel vehicles. Reason : Catalytic converters greatly reduce pollution caused by automobiles.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
Explanation:
\({\rm{SPM}}\) (Suspended Particulate Matter) is defined as particles floating in the air with a diameter below \(10 \mu \mathrm{m}\). Studies have shown that high \({\rm{SPM}}\) concentrations in the air can have a detrimental impact on respiratory organs. \({\rm{SPM}}\) generation from natural sources (e.g., volcanoes or dust storms) and human activities (vehicles, incinerators and industrial plants). Catalytic converters is a devices designed to reduce the amount of emissions from automobiles. The current (so-called threeway) systems use a heated metal catalyst to reduce the emissions of carbon monoxide \({\rm{(CO)}}\), hydrocarbons, and nitric oxide \({\rm{(NO)}}\), all of which contribute to the formation of photochemical smog.
