Solution. The correct option is B carbonisation. The forests got buried under the soil. The temperature rose as they got deeper and deeper. Under high pressure and high temperature, dead plants got slowly converted to coal. As coal contains mainly carbon, the slow process of conversion of dead vegetation into coal is called carbonisation.
