Solution

The correct option is B Zymase.
Zymase is an enzyme complex produced by fungi and occurring naturally by yeast cells. Zymase is responsible for the fermentation of sugars into ethanol and carbon dioxide. The rate of activity varies from one strain to another strain of yeast.
Thus, the correct answer is option B.
