- When a sprinter runs, their muscles may not get enough oxygen to support aerobic respiration.

- Lactic Acid: This is produced during anaerobic respiration when oxygen is scarce, causing muscle cramps and pain. Correct Answer

- CO₂: Carbon dioxide is a byproduct of aerobic respiration and doesn't accumulate to cause cramps.

- Pyruvic Acid: It's an intermediary in glycolysis and converts to lactic acid in anaerobic conditions but doesn't accumulate itself.

- Ethanol: This is not involved in muscle metabolism in humans.
