Answer:
D. By diffusion across a capillary wall
Explanation:
D is the best answer because gas exchange takes place in our lungs. Our lungs have alveoli which have a network of tiny blood vessels called capillaries, here the O2 diffuses the capillary wall to enter the bloodstream, and similarly CO2 diffuses out and we exhale it our from our lungs.

Answer:
Benefits:
In a lab, scientists can control the conditions according to their research and study. This allows them to focus on a single perspective.
On the other hand, in a natural setting there are complex interactions due to which focusing on a single attribute can be difficult.
Drawbacks:
Ina laboratory experiment, we cannot control every variable which might be having an effect on our concerned subject as compared to a natural setting. This is because lab experiments are performed in a controlled experiment. Hence, there might be difference of results in a lab experiment and nature.
