This is the actual question And the correct option is "A"
But I can't figure out why
Haldane effect plays more important role in promoting carbon dioxide transport than that of the Bohr's effect in promoting oxygen transport because
(a) oxyhaemoglobin is a stronger acid which donates hydrogen ion (H) which in turn displace carbon dioxide from blood
(b) carbaminohaemoglobin is a stronger acid which splits into hydrogen ion (H+) and bicarbonate (HCO) (c) carbon dioxide reacts with to form acid
that lowers the pH in tissue (d) carbon dioxide is less soluble in venous blood than in arterial blood.
