Solution

The correct option is B Solubility of $C O_{2}$ is higher than $O_{2}$
Diffusion is the process of movement of ions or molecules from a region of higher concentration to a region of lower concentration. The molecular arrangement of carbon dioxide makes it more soluble in blood compared to the solubility of oxygen. The solubility of carbon dioxide is 20-25 times higher than oxygen. Thus, higher the solubility higher will be the rate of diffusion.
