(B) Tyndal Effect
(C) Diffusion
(D) Electrophoresis

Answer 1

d) electrophoresis

I hope this answer will help you

Answer 2

When a potential difference (electricfield) is applied across two platinum electrodes immersed in a colloidalsolution, the particles of dispersed phase move towards either the positive or negative electrode. The movement of colloidal particles underthe action of electric field is known asElectrophoresis.
