Zymase is a complex mixture of enzymes found in yeast cells. It plays a crucial role in the process of fermentation. Zymase helps in the conversion of glucose into ethanol (alcohol) and carbon dioxide during anaerobic respiration (fermentation). This process is commonly used in the brewing industry to produce beer and wine and in baking to make bread rise.  

Diastase is an enzyme that helps in the breakdown of starch into simpler sugars, such as maltose. While diastase plays a role in carbohydrate digestion, it is not directly involved in the process of fermentation. 

Maltase is an enzyme that specifically catalyzes the hydrolysis of maltose into two molecules of glucose. It is essential for the digestion of maltose, which is a disaccharide sugar formed during starch digestion. However, maltase is not directly involved in fermentation.

This option is incorrect because only option c) Zymase is the correct enzyme present in yeast that helps in fermentation. The other options (a) Diastase and (b) Maltase, while important for other processes in the cell, are not directly involved in fermentation.
