all of the above

Explanation:

Passive transport is the movement of substances across a cell membrane without the use of energy. Diffusion (movement of particles from high to low concentration), osmosis (diffusion of water), and facilitated diffusion (diffusion with the help of transport proteins) all fall under passive transport. So all the given options are forms of passive transport.
