Question

Choose the option that correctly ranks the types of coals based on their carbon content.

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

Answer 1

The correct option is A

Anthracite > Bituminous > Lignite > Peat

Anthracite has the highest carbon content (about 94%), Bituminous coal has about 83% of carbon content, Lignite coal has about 67% and peat has lowest i.e. about 57% of carbon content. Hence the correct order of coal types based on their carbon content is:

Anthracite > Bituminous > Lignite > Peat
