Solution

The correct option is C
Oxygen will diffuse from alveoli into blood and carbon dioxide will diffuse from blood into alveoli

The partial pressure of oxygen is higher in the alveoli and lower in the blood. The partial pressure of carbon dioxide is higher in the blood and lower in the alveoli. So, oxygen will diffuse from alveoli into blood and carbon dioxide will diffuse from blood into alveoli.
