The correct answer are option d. "different shape (e. g. flat or ribbon shaped) " and option e. "larger internal surface area of the lungs".

Explanation:

The rate of diffusion of respiratory gases is one of the things that limits the size of organisms. One example is the respiratory system of the insects, which does not allow them to growth too much in size. However, some species of amphibians have adapted to overcome this limitation, with traits such as having a peculiar shape and having a large internal surface area of the lungs. For instance, giant salamanders are flat shaped and have a single lung which has a large internal surface area.
