Best answer
Right answer is (b) Diffusion

Easiest explanation: Brownian motion occurs in diffusion. The small particles in the fluid exhibit Brownian motion which is a random zig-zag motion of solid particles in the fluid. Diffusion is more significant in the filtration of gases than in the filtration of liquids.
