Choose the right sequential phenomena among the following during the delivery of O₂ from blood to tissue.
I. Absorption of CO₂ by the blood.
II. Reaction of absorbed CO₂ with H₂O to form H₂CO₃ within RBC and its conversion into H⁺ and HCO₃^- ions.
III. Reaction of absorbed CO₂ with H₂O in plasma to form H₂CO₃ and its conversion into H⁺ and HCO₃^- ions.
IV. Combination of H⁺ with haeme portion of HbO₂ to release O₂.
V. Combination of HCO₃^- with haeme portion of HbO₂ to form reduced haemoglobin and release of O₂.
