Answer:
B. bituminous
Explanation:
Bituminous coal is an organic sedimentary rock produced by compression of peat bog material by diagenesis and submetamorphics.
Bituminous coal has low moisture and high carbon content and hence used for the production of steel and cement, coke production an electricity generation.
Coking coal is a type of Bituminous coal are best used as fuel dource in metal industry having very narrow range of volatility and plasticity. Volatility is maintained by smelters to optimize the ease of burn rate, ignition, and energy output of the coal as this determines the burn rate of the coal.
Hence, the correct option is B. bituminous.
