The correct answer is option 4: Lactic acid. Lactic acid is a byproduct of anaerobic metabolism, which occurs when the body is working at a high intensity and cannot supply enough oxygen to the muscles. During intense exercise or physical activity, the body breaks down glucose into energy in the absence of oxygen, and lactic acid is produced as a result. This buildup of lactic acid in the muscles is associated with muscle fatigue. It can contribute to the burning sensation and discomfort experienced during strenuous exercise. It is important to note that lactic acid is temporary and is eventually cleared from the muscles when enough oxygen becomes available, allowing for recovery.
