Concept- Coal is a non-renewable source of energy and it gives us energy only when it is burnt. It burns to release greenhouse gases along with carbon dioxide.
Now, there are varieties of coal available. The duration and the heat intensity decide the percentage of the carbon content of coal.
Coal is classified into 4 types. They are: bituminous, peat, lignite and anthracite based on the amount of carbon, oxygen, moisture and hydrogen present in the coal.
Anthracite has 80 to 90 percent coal content which is why it is considered to be the best type of coal. It contains a very small amount of impurities.
Hence, the correct answer is option (2).
