Solution

The correct option is C Osmosis
Osmosis is the process by which solvent passes through a semipermeable membrane against the concentration gradient due to the osmotic pressure.

Whereas, diffusion, facilitated diffusion and reverse osmosis occur along the concentration gradient, i.e., from high concentration to low concentration.
