Answer:

The option which is incorrect is B) more CO 2 dissolves in blood plasma than is carried in the red blood cells.

Step-by-step explanation:

All the options here except B) are correct, as CO 2 which is also know as carbon dioxide, it is know to be more soluble than oxygen in the blood as it is said that almost 5% - 7% of CO 2 gets dissolved in the plasma . Carbon dioxide is found in greater concentrations in venous blood than the arterial blood. Through the bicarbonate buffer system, which allows a less change to the pH of the body system ,and through this it allows a person to live at high altitude places by regulating the amount of carbon dioxide. So we can say that its accumulation in the blood is linked with a decrease in pH. But more of the CO 2 doesn't dissolve in the plasma than is carried in the plasma as only 5-7 % of CO 2 is dissolved in plasma.
