Correct option is C. agricultural burning
Particulate matter is the sum of all solid and liquid particles suspended in air, many of which are hazardous. This complex mixture contains for instance dust, pollen, soot, smoke, and liquid droplets.
Some of the industries that use these processes and produce particulate matter are brickworks, refineries, cement works, iron, and steel smelters, quarries, and fossil fuel power plants.
Burning this agricultural waste, however, also releases black carbon, a type of fine particulate matter formed from incomplete combustion.
