C. Is an ethanol-gasoline mixture

Explanation:

E-85 is a designation used to represent a combination of ethanol and gasoline. It indicates an ethanol content of 85% and a gasoline content of 15%. Most countries with cold temperatures practice this mixture of ethanol with gasoline, because, ethanol makes it hard for the engines of vehicles to crank.

A major agricultural produce used in the production of ethanol is corn which undergoes fermentation. Some countries who use E-85 as a source of fuel include; the United States, as well as Sweden.
