Solution

The correct option is C Is anaerobic and produces carbon dioxide.
Anaerobic respiration in plant cells and some microorganisms (such as yeast) produces ethanol and carbon dioxide. It can be summarised by the following equation: glucose ethanol + carbon dioxide (+ energy released).
Therefore, the correct answer is option C.
