A Correct answer
Explanation

Yeast (Saccharomyces cerevisiae) is a fungus used in baking because it ferments sugars present in dough, producing carbon dioxide gas that makes the bread rise and become fluffy. Rhizopus is a mold that causes rotting, green algae are photosynthetic organisms not used in baking, and Penicillium is used for antibiotic production, not baking.
