The soreness in muscles after intense exercise is due to the shift into anaerobic metabolism, leading to lactic acid production (A). This lactic acid can indeed be converted back into glucose by the liver once exercise intensity decreases, a process known as the Cori cycle (B). The mention of "O₂" in choice C seems to be a formatting or encoding error, but given the context of discussing muscle soreness and recovery, it's plausible to interpret this as referring to a need for increased nutrients or substances (like oxygen or vitamins) to aid in muscle recovery, even though the specific notation doesn't directly correspond to a known substance. Therefore, considering the context and the plausible interpretations, all the provided choices relate to the physiological responses and recovery processes of muscles after intense exercise.
