The right answer is B. Fermentation (alcoholic fermentation).
Alcoholic fermentation is a catabolic process, the first step of which is glycolysis, which gives ethyl alcohol to re-oxidize NADH. Alcoholic fermentation is a biological process of fermentation in the total absence of oxygen, by the activity of certain microorganisms, which produce carbohydrates, generally sugars such as glucose, fructose, sucrose, which is a substance having the empirical form of glucose, ie hexose, to produce an alcohol, such as ethanol, carbon dioxide as gas, and adenosine triphosphate (ATP) molecules that consume microorganisms in their own final products. metabolism.
