Answer:
b) more surface area for diffusion of gases.
d) more space to increase volume of inspired air
Explanation:
Logically both the options are correct, as both of these indicates for the same utility of alveoli but if you have to select any one then "b) more surface area for diffusion of gases" will be more accurate. Basically, the large number of alveoli are required to ensure that a sufficient quantity of oxygen gets to the body to smoothly run the process of respiration.
