The production of ethanol in yeast is an example of anaerobic respiration. Thus, the correct option is A.
What is anaerobic respiration?
The process in which glucose is broken down to obtain ATP in absence of oxygen is called anaerobic respiration. In this process, electron acceptors are used instead of molecular oxygen to produce energy.
Some examples of anaerobic respiration include alcohol fermentation, lactic acid fermentation and in decomposition of organic matter. The equation is glucose + enzymes = carbon dioxide + ethanol / lactic acid. Though it does not produce as much energy as aerobic respiration, it gets the job done.
