Solution
The correct options are
B D has greater carbon content than C.
D A has the highest carbon content.
Coal formation is a very slow process, and its composition changes with different stages in its evolution. The earliest material created in the formation of coal is Peat. It comes somewhere between a fossil fuel and biomass. Lignite is a low grade brown coal having about 60 to 70 percent carbon. It is soft and has high moisture content. The next type of coal is bituminous coal with carbon content ranging from 69 to 86%. Finally, there is Anthracite, with more than 86% carbon content.
