Which of the following is an example of macromolecular colloid?

Step-by-step solution

Macromolecular colloids are formed when large molecules (macromolecules) having colloidal dimensions are dispersed in a suitable dispersion medium. Examples include naturally occurring macromolecules such as starch, cellulose, proteins, and enzymes, as well as man-made polymers like polythene, nylon, and polystyrene. Soaps and detergents are examples of associated colloids (micelles), which are formed by the aggregation of a large number of ions in concentrated solutions.
