The highest grade and best quality coal is-

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

Answer: B

Anthracite is the highest grade of coal, about 90 per cent carbon.

It is hard, black and lustrous, burns with almost no smoke and gives out the most heat. The rank descends through bituminous coal and lignite to peat, which is barely coal at all.
