Solution

The correct option is C 40% to 60 %
Coal is classified into three ranks based on carbon content in it. Continuous transformation of the coal leads to increased carbon content, the coal which has the least carbon content is Peat(40-60 %), which transforms into lignite (65-70%) to bituminous coal (76-86% ) and finally anthracite which is the purest form of coal (85-95%).
