The answer to this is Facilitated Diffusion. Facilitated diffusion is the process by which the passive transport of molecules and ions through a passageway going to the integral membranes. Usually, the molecules that would need to undergo this process would move in and out of the cell membranes. Some of the most common ones are sodium ions, potassium ions, and glucose.
They would need to use carrier proteins in order to get to their needed location easily within the body. The other processes that are given as options are used for other purposes. For example, osmosis is another process that happens in the body but this is needed by solvent molecules.
Facilitated diffusion is the transfer of molecules from a higher concentration to lower concentration (passive transport) through the proteins on the membrane. Molecules that enter through the proteins are often too large or ionic/polar to enter straight through the phospholipid bilayer. These are also the only molecules which can undergo active transport.
