Farming is considered as the major source of air pollution due to man. This is the man-made source of air pollution which allows the particles to enter the atmosphere. The movement of tractors will cause the soil particles to rise up in the air. The particles from the fertilizers and pesticides spray enter the atmosphere. Also during harvesting and husking, the small particles in the form of pollens and husks can result in air pollution. 
Thus, the correct answer is option B.
