The correct options are
A Alcohol
B Vinegar
D Lactic acid
Some organisms cannot live in the presence of oxygen. Such organisms perform anaerobic respiration for energy production. The anaerobic breakdown of pyruvic acid is called fermentation. Microorganisms break down pyruvic acid to form various products like vinegar, alcohol, organic acids, lactic acid etc. Lactic acid is also formed during anaerobic respiration in muscle cells.
