The fermentation of C6H12O6 will produce CO2 and 1. C3H5 (OH) 3 2. C2H5OH 3. Ca (OH) 2 4. Cr (OH) 3

Answer is "2 - C₂H₅OH".

Fermentation is a process which is used to produce energy from sugars (glucose, sucrose and fructose) in the absence of oxygen.

Fermentation with the glucose releases energy by producing carbon dioxide (CO₂) and ethanol (C₂H₅OH) as its byproducts.

The reaction is

C₆H₁₂O₆ → 2C₂H₅OH + 2CO₂ + energy

Fermentation of Glucose produces Carbon diOxide and Ethyl Alcohol (C2H5OH)
