When the movement of dispersed particles is restricted,the movement of the dispersion medium under the influence of an electric field is called:

Lyophilic sols are more stable than lyophobic sols because:

The charges on the colloidal $CdS$ sol and $TiO_2$ sol are,respectively :

Which among the following is $NOT$ an example of a one-dimensional nanostructure?

Provide information about the charge on colloidal particles.

Consider the following statements related to colloids.
$(I)$ Lyophobic colloids are not formed by simple mixing of dispersed phase and dispersion medium.
$(II)$ For emulsions,both the dispersed phase and the dispersion medium are liquid.
$(III)$ Micelles are produced by dissolving a surfactant in any solvent at any temperature.
$(IV)$ Tyndall effect can be observed from a colloidal solution with dispersed phase having the same refractive index as that of the dispersion medium.
The option with the correct set of statements is
