The structural organization of the lung is meant to maximize its surface area to increase gas diffusion. Due to the enormous number of alveoli (approximately 300 million in each human lung), the surface area of the lung is very large (75 m2). The large surface area increases the amount of diffusion.
So, the correct answer is option B.
