  • D Trachea ✔ ✖
Correct Answer

Explanation

Gas diffusion, which is the exchange of oxygen and carbon dioxide between the bloodstream and the air, takes place in the alveoli. The alveoli are small, balloon-like clusters located at the end of the bronchioles in the lungs. They are surrounded by capillaries, which allow for the exchange of gases between the lungs and the bloodstream. The walls of the alveoli are thin and moist, allowing for efficient diffusion of gases. Therefore, option A is the correct answer.
