The answer is A to this question
Facilitated diffusion is the process of moving molecules across the membrane with the help of transport proteins to make the transportation of the molecules a lot easier and smoother.
Simple diffusion, however, does not have the assistance of transport proteins. Simple diffusion takes place when molecules move from a high concentration (of said molecule) to a low concentration.
The difference: Facilitated diffusion has the help of transport proteins while simple diffusion does not.
