The correct answer is d. glucose.
Grapes contains sucrose which is made up of its monomers glucose and fructose. On mixing yeast with grapes, alcoholic fermentation occurs in which glucose is first converted into pyruvate. In the absence of oxygen (anoxygenic conditions), pyruvate can be converted into ethanol and carbon dioxide through the alcoholic fermentation by yeast. Thus, glucose is the source of carbon dioxide.
