Answer is Right!
Answer is Wrong!
The correct answer is C. Dolomite.
Lignite, bituminous, and peat are all coal varieties. Lignite is the lowest grade of coal, and it is brown in color. Bituminous coal is a higher grade of coal, and it is black in color. Peat is a type of coal that is formed from plant material that has been buried and subjected to heat and pressure over time.
Dolomite is a type of rock that is composed of calcium magnesium carbonate. It is not a coal variety.
