The correct option is D Lactate fermentation
Anaerobic respiration or fermentation can be of two types : lactate fermentation and ethanol fermentation. Lactate fermentation produces lactic acid only as pyruvic acid produced in glycolysis is directly reduced by NADH to form lactic acid and no carbon dioxide is produced. Alcoholic fermentation involves conversion of pyruvate to acetaldehyde, hence, carbondioxide is released.
