Answer: Option C
Step-by-step explanation:
A person has the part of lungs removed during the surgery and due to this surgery the number of alveoli in the body of the person will get reduced.
The bronchi is the main passage towards the lungs so the upper part will not be disturbed. As the lungs contains alveoli, there will be a reduction in the gas exchange between the blood and alveoli.
The rate of diffusion will decrease in between alveoli and blood.
