Answer

A

Explanation

Bakers yeast (Saccharomyces cerevisiae ) is added to flour during kneading. Yeast secretes enzymes like amylase (change some starch to maltose), maltase (maltose to glucose ) and zymase (glucose to ethyl alcohol and `CO_(2)` Leavened dough is baked and both alcohol and `CO_(2)` evaporate. The bread becomes soft and porous.
