Solution

The correct option is A Alcoholic fermentation
The breakdown of glucose to form ethanol and carbon dioxide is known as alcoholic fermentation. This takes place in the cytoplasm of cells. The substrate is glucose which undergoes glycolysis to form pyruvate. This pyruvate is then converted into acetaldehyde after the removal of one carbon and then ethanol is formed along with carbon dioxide.
So, the correct option is 'Alcoholic fermentation'
