C Correct answer
Explanation

During aerobic respiration, each carbon atoms in a glucose molecule is completely oxidized. Each oxidized carbon is released, along with two oxygen atoms, forming a molecule of carbon dioxide. Glucose contains 6 carbon atoms, thus the number of carbon dioxide molecules produced by the oxidation of one molecule of glucose during aerobic respiration is 6.
