Answer 1

The correct option is C Both A and B

• Yeast uses the sugars and oxygen in dough to produce more yeast cells and carbon dioxide gas. They also have higher rate of multiplication.
• The carbon dioxide makes the dough rise which gives the bread a light and spongy texture.
• Therefore yeast is used for the leavening of bread and other bakery products.
