Answer:

A. High concentration of oxygen in the blood; high concentration of carbon dioxide in the body tissues

Explanation:

Diffusion occurs from a region of higher concentration to a region of lower concentration. Diffusion occurs against a concentration gradient.

High concentration of oxygen in the blood causes oxygen to leave the blood and enter body tissues. High concentration of carbon dioxide in the body tissues causes carbon dioxide to leave body tissues and enter the blood.
