Fermentation products produced by the yeast are:

Explanation

In yeast fermentation, sugars are converted into ethyl alcohol (ethanol) and carbon dioxide (CO2) in the absence of oxygen. This process is known as alcoholic fermentation. The CO2 produced can be observed as bubbles, which is why this process is used in baking and brewing. Option D is correct because it accurately describes the products of yeast fermentation. Option A is incorrect because water is not a typical product of fermentation. Options B and C are incorrect because methyl alcohol is not produced by yeast, and option C further includes oxygen, which is not involved in anaerobic processes like fermentation.
