A. Peat
B. Bituminous
C. Anthracite
D. Lignite

Answer 1

Hint – The quality of coal or you can say rank of coal is based on the amount of the plant converted into carbon. Based on the content of carbon present coal is distributed into various types of coal.

Complete step-by-step answer:
We have to answer which coal contains the highest percentage of carbon.
Now, the coal is divided into different types of coals based on the content of carbon present in them.
So, the types of coal are mentioned below along with the percentage of carbon present in them-

1. Anthracite – 90 % carbon
2. Bituminous – 70 % carbon
3. Lignite – 40 % carbon
4. Peat – 28 % carbon

Therefore, as we can see the highest percentage of carbon is in Anthracite.
Hence, the correct option is C.

Note – Whenever such types of questions appear, write the types of coal as mentioned in the solution and then see what percentage of carbon is present in each type. As it is given in the solution that anthracite has the highest percentage of carbon.
