    Answer : Option C

    Explanation :

    Peat contains recognizable traces of the original plant material. Initially the peat is converted into lignite or ‘brown coal’ - these are coal-types with low organic maturity. In comparison to other coals, lignite is quite soft and its colour can range from dark black to various shades of brown.
