Answer 1

The answer is (c).
The process of conversion of sugar into alcohol is called fermentation.

Fermentation is the process in which yeast breaks down sugar into alcohol and carbon dioxide.However, similar processes take place in the leavening of bread ($C{O}_2$ produced by yeast activity) and in the preservation of sour foods with the production of lactic acids such as in sauerkraut and yogurt. Other widely consumed fermented foods include vinegar, olives and cheese.
