Solution

The correct option is D Assertion is incorrect but Reason is correct

Macromolecular solutions are polymers dissolved in a solvent, Starch, proteins, enzymes, and cellulose are the naturally occurring macromolecular colloids.
Colloids, due to the formation of aggregates (called micelle) of small particles, called aggregate or associated colloids. Soap and detergents are an example of associated colloids.
Thus Assertion is incorrect and Option D is correct.
