A) ethanol
B) carbon dioxide
C) oxygen
D) spores
E) sugar
Carbon Dioxide
A gas that is colorless and without smell, created when carbon and organic substances are burned and during the breathing process. This gas is naturally occurring in the atmosphere and taken in by plants for the process of photosynthesis.
Ethanol

Final Answer :
B
Explanation :
Yeast release carbon dioxide during the process of fermentation, which gets trapped in the dough causing it to rise. Ethanol is also produced, but it evaporates during baking. Oxygen is consumed during fermentation, and spores do not contribute to the rising of the bread. Sugar is consumed by yeast during fermentation, but it is not what causes the bread to rise.
