Which product is collected after fuel oil in the sequence?

Explanation:
The question tests understanding of fractional distillation in a refinery. In this process, crude oil is heated and its components separate by boiling point in a column: lighter fractions vaporize and rise, condensing at higher levels as gases or liquids, while heavier fractions with much higher boiling points stay as vapor until they reach the bottom and exit as the residue. Bitumen is the heaviest, most viscous material and remains as this bottom residue, collected last. So after the fuel oil fraction, the next product to be collected is the thick, viscous bitumen.
