Detailed explanation-1: -So, the correct answer is ‘Carbon dioxide’
Detailed explanation-2: -The puffed up appearance of dough or softness and porous is due to the production and release of CO2.
Detailed explanation-3: -Carbon dioxide (CO₂) gas released during fermentation process.
Detailed explanation-4: -During fermentation, carbon dioxide is produced and trapped as tiny pockets of air within the dough. This causes it to rise. During baking the carbon dioxide expands and causes the bread to rise further. The alcohol produced during fermentation evaporates during the bread baking process.
Detailed explanation-5: -The dough becomes puffy due to the presence of carbon dioxide liberated by bacteria during fermentation. Fermentation is anaerobic respiration performed by bacteria in the absence of oxygen.
