B: eventually becomes balanced/equilibrium on both sides of a membrane.
|| ✪ Explanation ✪ ||
Diffusion is the movement of molecules from a high to a low concentration. The effect of diffusion on different substances' concentrations is balance/ equilibrium on both sides of a membrane. In the process of the movement of molecules, the concentration becomes balanced. A typical example of diffusion is a perfume sprayed inside a room. The smell of the perfume will eventually be balanced in the entire room.
