Answer
Cytoplasm and Oxygen deficient muscle cells
Reason — Glycolysis (Glucose → Pyruvate + energy) takes place in the cytoplasm of the cell and when oxygen is scarce, pyruvate is converted to lactic acid in oxygen-deficient (anaerobic) muscle cells, releasing a small amount of energy.
Hence the sites for (a) and (b) are cytoplasm and oxygen-deficient muscle cells respectively.
