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

Answer 1

The correct option is A Lignite

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> Lignite is a low grade brown coal with carbon content of about 60 to 70%. Peat is not actually coal, but rather the precursor to coal. Bituminous coal is of higher quality than lignite and Sub-bituminous coal, but of poorer quality than anthracite.
