Solution
The correct option is C Alcohol
Our early ancestors used microorganisms to make cheese, yoghurt and bread. They also made alcoholic drinks like beer and wine. All of these foods and drinks are made by fermentation. Fermentation is the process that many microorganisms (yeasts, moulds and bacteria) use to convert sugars into energy. The products generated from fermentation affect the nature of the food that the microorganism is in - carbon dioxide causes bread to rise, lactic acid makes yoghurt sour, and alcohol is produced in the formation of beer and wine. Fermentation was probably discovered by accident, and our early ancestors didn’t know how it worked. Some societies thought fermentation was a miracle or gift from their god.So the correct option is 'alcohol'.
