Show answer & explanation
Correct answer: C
Concept
A fuel blend is named by the components combined to make it.
Ethanol–petrol blends are oxygenated motor fuels, and their established names often combine parts of the component words.
Application
Here the components are petrol (gasoline) and ethanol (ethyl alcohol). The established portmanteau joins “gaso-” from gasoline with “-hol” from alcohol, producing “Gasohol”.
Contrast
Gasol contains the gasoline-derived opening “gas-” and a short “-ol” ending.
Petrohol joins the petroleum-derived opening “petro-” with the alcohol-derived ending “-hol”.
Gasohol joins the gasoline-derived opening “gaso-” with the alcohol-derived ending “-hol”.
Ethopetrol places an ethanol-derived opening “etho-” before “petrol”.
Cross-check
The U.S. Environmental Protection Agency identifies gasoline containing 10% ethanol as gasohol or E10. This independently confirms the conventional name.
Result
Therefore, the ethanol–petrol mixture is called Gasohol.
