Vedclass · Answer

(C) The correct answer is $C$. During intense physical activity,the rate of oxygen supply by the lungs falls short of the metabolic requirements of the muscles. As a result,the muscles switch to anaerobic respiration,leading to the accumulation of lactic acid. After the exercise,the body requires extra oxygen to oxidize this accumulated lactic acid and restore energy reserves ($ATP$ and phosphocreatine) in the muscles. This extra amount of oxygen consumed after exercise to restore the body to its resting state is known as 'oxygen debt' or 'muscle recovery' phase.
