Best answer
Correct option is (b) When humans started using firewood

The best I can explain: The origin of air pollution on earth can be traced when humans started using firewood as a means of cooking and heating food items. Back in 400 BC itself, Hippocrates mentioned air pollution. As the years passed air pollution keeps on increasing.
