Hello! I'd be happy to help with your question.
The correct answer is:

Explanation:
1. Fermentation is the process of producing alcohol, like ethanol, by using living organisms such as yeast.
2. In this case, when yeast is grown in a sugar solution, it undergoes fermentation to produce ethanol as a byproduct.
3. This process is commonly used in the production of alcoholic beverages like beer, wine, and spirits.
4. Fermentation is a biological process that breaks down sugars into alcohol and carbon dioxide through the action of yeast or bacteria.
