Explanation

Coal is a fossil fuel formed from dead plant matter that got buried deep inside layers of soil. The formation of coal involves various biological and geological processes which occur at very high temperature and pressure over a long period of time. But the formation of coal doesn't cause any air pollution.
Only statements A and C are correct

Hence option
