Explanation:

In alcoholic fermentation, glucose is first converted to pyruvate through glycolysis. Then, under anaerobic conditions, pyruvate is decarboxylated to acetaldehyde, and acetaldehyde is reduced to ethanol. Acetyl - CoA is involved in aerobic respiration (the link reaction between glycolysis and the Krebs cycle). Acetaldehyde is an intermediate in alcoholic fermentation, not the final product. Lactate is the product of lactic acid fermentation. Pyruvate is the end - product of glycolysis and is further metabolized in fermentation.

Answer:

C. ethanol
