Answer 1

Answer:

A. A bottle of alcoholic drink.

Explanation:

Lactic acid fermentation differs from ethyl alcohol fermentation in that lactic acid, rather than ethanol, is the resulting by-product. When exposed to oxygen, lactic acid molecules break down into carbon dioxide and water. When used in food production, this lactic acid breaks down sugars, preventing food from spoiling.
