Q1. Which coal contains the highest amount of carbon?
A Lignite
B Peat
C Bituminous
D Anthracite Correct
Explanation
Anthracite is the highest-rank coal and has the greatest carbon content among the listed types. It is hard, lustrous, and burns with comparatively less smoke. Bituminous coal has high carbon, but it ranks below anthracite. Lignite is a lower-rank brown coal with more moisture and less carbon. Peat is the earliest stage in coal formation and has the least developed carbon concentration among these choices. Therefore, the coal with the highest carbon amount is anthracite.
