The correct option is C 97
Blood is the medium of transport for oxygen and carbon dioxide. About 97 per cent of oxygen is transported by RBCs in the blood. The remaining 3 per cent of oxygen is carried in a dissolved state through the plasma. Nearly 20-25 per cent of carbon dioxide is transported by RBCs, whereas 70 per cent of it is carried as bicarbonate. About 7 per cent of carbon dioxide is carried in a dissolved state through plasma.
