    Answer : Option A

    Explanation :

    All example of a mineral occurring as layers in sedimentary rocks is Lignite. Lignite, often referred to as brown coal, is a soft, brown, combustible, sedimentary rock formed from naturally compressed peat. It is considered the lowest rank of coal due to its relatively low heat content. It has a carbon content around 60–70 percent.
