Solution(By Examveda Team)

Dispersion of one substance in the medium of another substance is called Diffusion.
Diffusion is the net movement of anything generally from a region of higher concentration to a region of lower concentration.
It is the gradual movement/dispersion of concentration within a body, due to a concentration gradient, with no net movement of matter or substance.
