Why the answer is C, and why the others tempt you.
Aerobic respiration proceeds in three main stages in order: glycolysis (in the cytoplasm), the Krebs cycle (in the mitochondrial matrix), and the electron transport chain (on the inner mitochondrial membrane). Glycolysis converts glucose to pyruvate, which enters the Krebs cycle after being converted to acetyl-CoA. The electron transport chain then uses the electron carriers produced to generate the bulk of ATP.
