Solution
The correct option is B Anthracite
- Anthracite is obtained at the last stage in the formation of coal. It contains 92-98% carbon. It is black in colour and hard.
- The coal formation process starts from dead plants and animals. They undergo many geological processes in the presence of heat and pressure over the years and converts to peat to lignite to bituminous and finally to anthracite.
