Which of the following represents a macromolecular colloidal particles?

In this type of colloid, a solution is created by the combination of the macromolecules and a suitable solvent. The particle size of this macromolecular solution is within the range of colloidal particle size. This solution is also known as the macromolecular colloids. 

Here, incredibly stable colloids are produced that, in many respects, mimic the solution.
Examples of naturally occurring macromolecular colloids include cellulose, starch, proteins, and enzymes, whereas synthetic macromolecules include polyethene, rubber, and other substances.
