Milk is an example of :

Explanation

Milk is an example of an emulsion found in nature. In milk, fat is present in the form of an emulsion. An emulsion is a colloid of a liquid dispersed in a liquid. Therefore, an emulsion is an example of a colloidal solution. A colloidal solution is formed by a dispersed phase and a dispersion medium. The solute-like component (dispersed particles) present in colloidal form is called the dispersed phase, and the component in which the dispersed phase remains suspended is called the dispersion medium. Colloidal solutions are classified on the basis of the physical state of the dispersion medium (solid, liquid, or gas) and the dispersed phase. Hence, in this question, both options (b) and (c) are correct. As the most appropriate option, students may choose “emulsion”.
