Why is the molecular mass determined by measuring colligative property in case of some solutes is abnormal?

Question

Why is the molecular mass determined by measuring colligative property in case of some solutes is abnormal? (A) Due to association or dissociation of solute molecules (B) Due to insolubility of solute molecules (C) Due to decomposition of solute molecules (D) Due to large size of solute molecules

Due to association or dissociation of solute molecules there is a change in number of particles. Since colligative properties depend on number of particles there is a change in molecular mass.
