hey
i think the answer is D because glucose is added to yeast in a beaker and boiled the contents and cooled it without shaking...so that co2 water and ethanol is produced
it is not C because boil water shouldn't be used
it is not A because water is not necessary in that experiment
it is not B because fermentation occurs in the absence or little presence (sometimes) of oxygen
