B. Type of sugar

Explanation:

This so because I had this exact question on USA test prep and I chose it and it was correct.

Diamond Hartman · Answer 2

The correct answer is D) Rate of fermentation.

Explanation:

Carbohydrates are fermented by yeast to form alcohol by alcoholic fermentation.

Now if the effects of different carbohydrate molecules are tested on yeast then the yeast will ferment different sugar molecules at different rate.

As a result the rate of fermentation will be the independent variable of the experiment.
