Concept:Crude oil fractions are separated by their different boiling point ranges during fractional distillation.Explanation:Each fraction condenses at a specific temperature range in the fractionating column.Kerosene distills at about 200−250∘C.Petrol (gasoline) distills below 200∘C.Diesel distills between 250−350∘C.Bitumen remains as a residue at temperatures above 370∘C.Therefore, the fraction collected at 200−250∘C is kerosene.Answer:C. kerosene
