    D. All of the listed choices represent facilitated diffusion

    Explanation:

    Facilitated diffusion across a membrane is also called passive - mediated transport or facilitated transport. It involves the spontaneous passive movement of ions or molecules past a cell membrane through certain membrane protein. This process is brought about by channel or carrier proteins. It is used by ions that cannot easily cross the phospholipid bilayer
