Answer:

C.-lower than the concentration of oxygen in the air or water.

Explanation:

In the process of diffusion a substance moves from its region of higher concentration to its region of lower concentration. So oxygen will easily diffuse from air or water where its concentration is higher to an animal's bloodstream where its concentration is lower.
