Abnormal colligative properties are observed only when the dissolved non-volatile solute in a given dilute solution

Question

Abnormal colligative properties are observed only when the dissolved non-volatile solute in a given dilute solution (A) is a non-electrolyte (B) offers an intense colour (C) associates or dissociates (D) offers no colour

As the colligative properties depend only upon the number of particles of solute, so if the non-volatile solute dissociates or associates in the solution, the value of colligative properties deviates ie, abnormal colligative properties are obtained.
