The answer is D. Coal is considered as a nonrenewable resource because it takes million of years to form. Coal is formed by the alteration of peat chemically and physically. The process of coal formation is called coalification. During this process, peat experiences a lot of processes like heat, a lot of pressure and bacterial decay where oxygen is forced out and what's left is carbon deposits which in due time forms coal.
