Solution

The correct option is C Low oxygen concentration and high CO2 concentration
When oxygenated blood reaches the different tissues, the partial pressure of oxygen is higher (95 mm of Hg) than that of the body cells (40 mm of Hg) and the partial pressure of carbon dioxide is lesser in the blood (40 mm of Hg) than that of body cells (45 mm of Hg). The, oxygen diffuses from the capillary blood to the body cells through tissue fluid and carbon dioxide diffuses from the body cells to the capillary blood via tissue fluid. This makes the blood deoxygenated, which is carried to the heart and then to the lungs.
Thus the correct answer is option A.
