Correct Option (a) simple diffusion
Explanation:
Oxygen diffuses from alveoli to deoxygenated blood and CO2 diffuses from deoxygenated blood to alveoli by simple diffusion. Diffusion is defined as, the flow of the substance (gases) from a region of their higher concentration to a region of lower concentration.
