Which fuel is partially carbonized and is considered as a primary stag

1.	Which fuel is partially carbonized and is considered as a primary stage in coal formation?(a) Coal bitumen(b) Anthracite(c) Peat(d) LigniteThis question was posed to me during an online exam.I'd like to ask this question from Types of Fuels in portion Steam Power Plant of Energy Engineering
Answer» The correct choice is (c) Peat Best explanation: Peat is partially carbonized and DECOMPOSED MATERIAL formed mainly due the transformation of buried vegetation. It is considered as the primary stage in the formation of the coal. It is spongy substance with high moisture content (upto 80%). Hence it has to be dried before use. In DRY FORM, it has a calorific value of about 14560 KJ/kg. It consists of 58% C; 6.3% H2; 30.8% O2; 0.9% N2 and 4% ash.
