Question

Bread Dough To make bread dough, a cook mixes flour, water, salt and yeast. After mixing, the dough is placed in a container for several hours to allow the process of fermentation to take place. During fermentation, a chemical change occurs in the dough: the yeast (a single-celled fungus) helps to transform the starch and sugars in the flour into carbon dioxide and alcohol.
(a) Fermentation causes the dough to rise. Why does the dough rise?
A. The dough rises because alcohol is produced and turns into a gas.
B. The dough rises because of single-celled fungi reproducing in it.
C. The dough rises because a gas, carbon dioxide, is produced.
D. The dough rises because fermentation turns water into a vapour​
