Solution
The correct option is C both A and B
Human activity and natural processes can both generate air pollution.The natural form of particulate matter is the result of volcanic dust and gases, mineral dust and sea-salt crystals. Another class of natural particulate matter is smoke from forest and grass fires. Living plants release pollens and spores into the air, which are organic compounds.
Man-made particulate matter comes from many sources, but its major source is the combustion of hydrocarbon fuels—petroleum products, coal, peat, and wood. Combustion of solid wastes is another source. Other kinds of matter introduced into the atmosphere are industrial chemicals, fly ash, refining fossil fuels, mining and smelting ores, as well as pollutants discharged through quarrying, farming activities, etc. Use of various types of solvents and also radioactive elements are the cause of air pollution created by man.
