Solution

The correct option is A They carry about 20-25 percent of CO2.
23% of CO2 is combined with haemoglobin and transported as carbaminohaemoglobin.
About 70% of CO2 is transported as bicarbonates.
7% of CO2 gets dissolved and transported through the plasma.
Only 1.5 percent of oxygen in the blood is dissolved directly into the blood itself. Most oxygen, 98.5 percent, is bound to a protein called hemoglobin and carried to the tissues.
