Liquefied petroleum gases are obtained from which part of the fractional distillation process?

The correct option is The fraction that condenses at the lowest temperature.

The correct option is The fraction that condenses at the lowest temperature. The fraction that condenses at the lowest temperature is correct because it directly supports the approved learning objective to identify common fuels produced from crude oil, such as petrol, diesel oil, kerosene, heavy fuel oil and liquefied petroleum gases. This belongs to Fractional distillation and petrochemicals within Carbon compounds as fuels and feedstock, so the answer must use the correct organic chemistry context. The other options are incorrect when they confuse the organic family, formula type, reaction condition, product, or property being tested. Keep molecular formula, structural formula, displayed formula, and general formula distinct. Do not confuse alkanes with alkenes, saturated with unsaturated, cracking with combustion, polymers with monomers, or hydrocarbons with oxygen-containing alcohols and carboxylic acids. When formulae are used, preserve the stored notation exactly and explain the GCSE chemistry idea in words rather than using unsupported displayed-formula diagrams.
