Which ingredient makes bread fluffy?

Correct option is B

The correct answer is (b) Yeast.
· Yeast is a key ingredient in making bread fluffy. It is a microorganism that ferments the sugars in the dough, producing carbon dioxide gas and ethanol.
· The carbon dioxide gas gets trapped in the dough's gluten network, causing the dough to rise and expand.
· During baking, the heat causes the gas bubbles to expand further, and the dough solidifies around them, resulting in a light and fluffy bread texture.
· Yeast also contributes to the flavor and aroma of the bread through the fermentation process.
