Explanation:

The question is about the movement of a substance directly through the plasma membrane along a concentration gradient. Simple diffusion is the process where molecules move from an area of higher concentration to lower concentration directly through the lipid bilayer of the plasma membrane, without the need for a transport protein. Exocytosis is for bulk transport out of the cell, osmosis is specifically for water, and facilitated diffusion requires a protein channel. So the correct process is simple diffusion.

Answer:

simple diffusion
