Crude oil is a complex mixture of hydrocarbon molecules that is separated into simpler fractions using a fractionating column. The diagram below shows a simplified industrial fractionating column where three fractions, PPP, QQQ, and RRR, are collected at different heights.

Which row in the table below correctly identifies the primary uses of fractions PPP, QQQ, and RRR?
Fraction PPP: fuel for aircraft | Fraction QQQ: fuel for diesel engines (trucks, trains) | Fraction RRR: surfacing roads and roofs
Fraction PPP: fuel for cars (petrol) | Fraction QQQ: fuel for aircraft | Fraction RRR: fuel for ships and power stations
Fraction PPP: fuel for diesel engines (trucks, trains) | Fraction QQQ: fuel for aircraft | Fraction RRR: surfacing roads and roofs
Fraction PPP: fuel for aircraft | Fraction QQQ: fuel for ships and power stations | Fraction RRR: fuel for central heating
