With regard to the assertion and reason, choose the correct option:
Assertion [A]: Suspended particulate matter (SPM) is a major pollutant released by diesel vehicles.
Reason [R]: Catalytic converters greatly reduce pollution caused by automobiles.
With regard to the assertion and reason, choose the correct option:
Assertion [A]: Suspended particulate matter (SPM) is a major pollutant released by diesel vehicles.
Reason [R]: Catalytic converters greatly reduce pollution caused by automobiles.
The correct option is B Both assertion and reason are true but the reason is not the correct explanation for the assertion
Particulate matter comprises solid particles and liquid droplets (aerosols) small enough to remain suspended in air such as smoke, dust, some metals, etc. Suspended Particulate Matter (SPM) contains particles with a diameter of less than 10 µm. SPM is generated from natural sources like volcanoes or dust storms and human activities such as vehicles, industrial plants, etc. Electrostatic precipitator can remove over 99 percent of the particulate matter present in the exhaust from a thermal power plant. Catalytic converter filters in vehicles can convert nitrogen oxides (NOx) to nitrogen and reduce potential hazards of nitrogen oxides.
