The answer would be C. Glycolysis. Aerobic respiration and Anaerobic respiration are the two types of cellular respiration. It breaks down glucose to produce certain chemical reaction and by products. To achieve this both of this cellular respiration uses glycolysis to produce ATP.
The answer to your question is C.Glycolysis Aerobic respiration is process involves oxygen. Anaerobic respiration doesn't use the oxygen. The first step in both Aerobic and Anaerobic respiration is Glycolysis. So Glycolysis is common between aerobic and anaerobic respiration
