Solution

The correct option is A ethanol or lactic acid

Alcoholic fermentation is called as lactic acid fermentation, it is anaerobic respiration that does not require oxygen. It is the process of release of energy by incomplete degradation of organic food hence end products are never fully inorganic. First glycolysis occurs and forms two molecules of pyruvate after that fermentation occurs, no oxygen involved and later forms ethyl alcohol and lactic acid.
So, the correct option is ' ethanol or lactic acid'.
