Which of the following is the process of converting sugar into alcohol?

Correct option is C

The correct answer is (C) Fermentation.

Explanation:
Fermentation is a biological process in which sugar is converted into alcohol and carbon dioxide by the action of yeast or bacteria. It is a fundamental process used in the production of alcoholic beverages, biofuels, and in food preservation.

Information Booster:

• Fermentation: It is crucial in industries like brewing, winemaking, and distillation. It also plays a role in the production of foods like yogurt and bread.
• Key Applications: Alcoholic beverages such as beer, wine, and spirits, as well as biofuels like ethanol, rely on fermentation for production.

Additional Information:

• Pasteurisation: A heat treatment process designed to kill harmful microorganisms in liquids such as milk and juice, not related to alcohol production.
• Bleaching: A chemical process used to whiten or lighten substances, but not connected to alcohol production.
• Oxidation: A chemical reaction involving the loss of electrons, which occurs in various processes but not directly in alcohol production.
