Solution
The correct option is B Bicarbonate
CO2 enters RBC after its diffusion into the blood at the tissues. A small amount is become attached to haemoglobin and forms carbaminohemoglobin. A major amount of the CO2 combines with water and forms carbonic acid. The carbonic acid dissociates into hydrogen ions and bicarbonate ions, which are then diffused out of red blood cells into the plasma. Thus, the majority of carbon dioxide is carried in form of bicarbonate ions. So, the correct answer is option B.
