Which reaction involving CO₂ predominates within erythrocytes in the pulmonary capillaries of the lung? A) HCO^-₃ combines with H⁺ to form H₂CO₃, which dissociates into CO₂ and H₂O. B) HCO^-₃ dissociates into H⁺, CO, and O₂. C) CO₂ combines with H⁺ to form HCO₂. D) CO₂ combines with water to form bicarbonate ion and carbonic acid.
