Correct Answer: B
Solution :
Particulate matter comprises solid particles or liquid droplets (aerosols) small enough to remain suspended in air such as smoke, dust, some metals etc. Suspended particulate matter (SPM) have particles with a diameter below\[10\,\mu \,m.\] SPM is generated from natural sources such as volcanoes or dust storms and human activities such as vehicles, industrial plants etc. Catalytic converter filters in the vehicle can convert nitrogen oxides \[(N{{O}_{x}})\] to nitrogen and reduce potential hazards of nitrogen oxides.
