Ответ:
C. Simple diffusion
Explanation:
Simple diffusion from a high to low concentration is the most direct method that ions or molecules can move across a cell membrane.
Through this method, no proteins are required for transport, and no energy is used.
The ion or molecule being transported directly moves across the cell membrane, without any other factors involved.
So, the correct answer is C. Simple diffusion
