Facilitated diffusion is a process where solutes move across a membrane from an area of high concentration to an area of low concentration with the help of transport proteins, without the expenditure of energy. This matches the description given in the question. Osmosis specifically refers to the movement of water across a semipermeable membrane, not solutes. Active transport involves the movement of substances against their concentration gradient and requires energy.
