DTrue only historically, not now
Answer
Correct Answer: Agree (the statement is correct)
Explanation
Concept/Approach
- Conventional commercial liquid fuels (gasoline/petrol, kerosene, diesel, furnace oil, LDO/HFO) are petroleum distillates or blends from crude-oil refining.
- Though alternative liquids like ethanol exist, classic textbooks typically classify commercial liquid fuels as petroleum derived.
Final AnswerAgree — in the usual engineering classification, commercial liquid fuels are derived from crude oil.
