The answer is C:BIOLOGICAL DIVERSITY.
INFORM ME IF I AM WRONG.
The model attached represents facilitated transport, which is answer choice D. In the model, there are protein channels, which allow molecules to pass through them if they're too large to fit through the aquaporins (making diffusion an incorrect answer.) We can eliminate active transport since ATP isn't used to control transport, and we can eliminate endocytosis as it is a form of active transport. The remaining answer would be facilitated transport, which is a form of passive transport. Hope this helps! :)
