उत्तर
Anthracite is the best quality coal.
Explanation:
Anthracite is considered the highest quality hard coal since it has the highest carbon concentration, ranging from 80% to 95%, and has few impurities. Because of its high carbon density and low moisture content, it burns cleanly with a brief blue flame, emits little smoke, and provides the most heat energy (calorific value) of any type of coal.
