Solution

The correct option is D Beer
Germinating barley seeds are used in the preparation of Beer. Yeast (Saccharomyces cerevicea) acts on the sugars of the barley seeds and converts it to ethanol and CO2. The CO2 is extracted and stored for later use, while the excess yeast is removed. The fermented broth, with a large amount of ethanol in it, is now called green beer. It is allowed to mature and develop a distinct flavor. After maturation, the liquid is filtered, pasteurized and the CO2 that was extracted earlier, is pumped back inside in order to give the beer the fizzy taste. Finally, the finished product is bottled and sold for consumption.
