A Correct answer
Explanation

Anthracite is the highest grade of coal, characterized by a high carbon content (often exceeding 85-90%) and low impurities. Bituminous coal has a lower carbon content, followed by lignite and then peat, which is the lowest grade. Higher carbon content results in a higher energy density and less smoke during combustion.
