Solution

The correct option is B diffusion
The exchange of gases takes place between the millions of alveoli in the lungs and the capillaries that envelop them. Inhaled oxygen moves from the alveoli to the blood in the capillaries and carbon dioxide moves from the blood in the capillaries to the air in the alveoli. This exchange occurs by the process of diffusion.
