Answer:
            Option-C, <u>STEEL</u> <span>is not a product of the fractional distillation of petroleum.

Explanation:
                   Petroleum is the mixture of Hydrocarbons *carbon and hydrogen containing compounds) present beneath the Earth's surface. Petroleum is formed from the remains of animals and plants beneath earth's surface in an anaerobic conditions.
                   Petroleum contains from small hydrocarbons (gases) to medium (liquids) and long chain hydrocarbons (Solids). These hydrocarbons are separated from each other by Fractional Distillation method (separation due to difference in boiling points)
                   Gasoline is a derivative of one of the fraction of petroleum used in internal combustion engines.
                   Jet Fuel is also derived from Kerosene and Naphtha fractions of petroleum.
                   While, Steel is inorganic Alloy (mixture of metals) composed of mainly Iron, Carbon and other elements.</span>
