Assertion (A): Oxygen gets bound to hemoglobin of blood present in capillaries around alveoli and gets dissociated at the tissues. Reason (R): Factors favorable for the formation of oxyhemoglobin are high pO2, low pCO2, lesser H+ concentration, and lower temperature, whereas in the tissues low pO2, high pCO2, high H+ concentration, and higher temperature are favorable for the dissociation of oxygen from oxyhemoglobin. In the context of the above statements, select the correct option:
