Air pollution on the road can be reduced by encouraging the use of CNG in vehicles. When used in vehicles as fuel, CNG produces fewer undesirable gases than petrol, diesel or propane. If we increase the number of vehicles on the road, then they will emit more of carbon emissions and smoke. This would cause more air pollution.Deforestation means cutting down trees and forests. Trees absorb harmful carbon dioxide from the air. If trees are cut down, they would not be able to absorb carbon dioxide, so carbon dioxide levels in air would go up. This would cause more air pollution. Hence, Option C is the correct answer.
