Colour is imparted to glass by mixing

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

Peptization is defined as:

Sodium stearate $CH_{3}(CH_{2})_{16}COO^{-}Na^{+}$ is an anionic surfactant which forms micelles in water. Choose the correct statement for it from the following:

Which of the following is true for a $Fe(OH)_3$ sol?

In emulsions,the dispersion medium and dispersed phase are
