Answer:
Option (B)
Explanation:
The sequential order of coal in term of its highly heated (most valuable) to least heated (least valuable) is given below-
Anthracite > Bituminous > Lignite > Peat
- Anthracite is a high-rank coal comprised of 90-95% of carbon content and only about 5% of oxygen and water content.
- Bituminous also high-rank coal comprised of 70-90% of carbon content and about 50-60% of oxygen and water content.
- Lignite is a low-rank coal and is comprised of 60-70% of carbon and about 30% of oxygen and 30-60% of water content.
- Peat is also a low-rank coal and is composed of less than 50% of carbon and about 50% of oxygen and nearly 70-80% of water.
According to the classification of coal, the amount of oxygen and water content increases from the higher grade coal to the lower grade, and the carbon content decreases from higher grade to the lower grade coal.
Thus, the correct answer is option (B).
