Answer:
A. A water molecule passes through a semi permeable membrane
Explanation:
Facilitated diffusion is the diffusion of a molecule without any assistance from a protein or protein channel.
In facilitated diffusion, a molecule will diffuse by itself through a semi permeable membrane, such as the cell membrane.
Answer choices B, C, and D are incorrect because they are all examples of facilitated diffusion. The molecules required assistance from a protein.
