The creation of ethanol by fermentation

Explanation:
Fermentation is a biological process where yeast converts sugars into ethanol and carbon dioxide. When plant materials rich in sugars—or materials that can be turned into sugars—are fermented, the ethanol produced is called bioethanol, a renewable fuel. The other options aren’t related to making ethanol: arable farming is about growing crops, an artesian aquifer is a pressurized underground water layer, and the asthenosphere is part of the Earth’s mantle. So fermentation yielding bioethanol is the concept being tested.
