Solution

The correct option is B Saccharomyces
Alcoholic fermentation is due to the activity of yeast.
In food manufacture, yeast is used to cause fermentation and leavening. The fungi feed on sugars, producing alcohol (ethanol) and carbon dioxide, in beer and wine manufacture the former is the desired product, in baking, the latter. In sparkling wines and beer, some of the carbon dioxide is retained in the finished beverage. The alcohol produced in bread making is driven off when the dough is baked. The fermentation of wine is initiated by naturally occurring yeasts present in the vineyards. One yeast cell can ferment approximately its own weight of glucose per hour.
