B Osmosis, because energy is not being used to move water molecules with the concentration gradient.Osmosis, because energy is not being used to move water molecules with the concentration gradient.
C Endocytosis, because a vesicle is being formed to bring molecules from outside the cell into the cell.Endocytosis, because a vesicle is being formed to bring molecules from outside the cell into the cell.
D Active transport, because energy is being used to move molecules against the concentration gradient.

The best statement that identifies the form of cellular transport described is:
**A**: Facilitated diffusion, because energy is not being used as a channel protein allows molecules to move with the concentration gradient.
Facilitated diffusion involves the movement of molecules across a cell membrane via protein channels without the use of energy, and it occurs along the concentration gradient. If the scenario involves water molecules specifically, response B (Osmosis) could also be correct, but without that context, A is the most appropriate choice.
