Correct: "A byproduct of fermentation" and also "A fuel source for the muscles."
Explanation: Lactic acid (lactate) is produced during anaerobic glycolysis (lactic acid fermentation) when oxygen is limited. Muscles (and the heart and liver) can take up lactate and convert it back to pyruvate for use as an energy source. It is not a protein and is not a component of aerobic respiration.
