Which of the following is not a fraction obtained from fractional distillation of crude oil?

Explanation:
Fractional distillation of crude oil separates the mixture into fractions based on boiling points. Lighter fractions with lower boiling points rise and are collected higher in the column as refinery gases, gasoline, and kerosene, while heavier fractions like diesel and lubricants are collected lower down. Ethanol isn’t a component of crude oil and isn’t produced by distilling it; it comes from fermentation (or from ethene) and is an alcohol, not a hydrocarbon fraction found in crude oil. So it does not appear as a fraction obtained from fractional distillation of crude oil.
