Best answer
Right answer is (b) Mitochondrial matrix

Easy explanation: Pyruvate oxidation takes place in the presence of oxygen inside the mitochondrial matrix and oxidized to acetyl Co-A. Pyruvate is produced in the glycolysis from where it enters to mitochondria with the help of transport protein.
