C Correct answer
Explanation

Yeast (Saccharomyces cerevisiae) is used in alcohol production through fermentation. It converts sugars into ethanol and carbon dioxide. Mushrooms are fungi used for food, Mucor is a bread mold, and algae are photosynthetic organisms - none produce alcohol through fermentation. Yeast's ability to ferment sugars makes it essential in brewing and winemaking.
