Solution

The correct option is C Electrophoresis
Colloidal particles carry electrical charges. When we apply an electric potential across two platinum electrodes dipped in a colloidal solution, the colloidal particles move towards the oppositely electrode. The movement of colloidal particles under an applied electric potential is called electrophoresis.
