How do solute particles increase boiling point?

[TT0]

The question is:

Which solution listed below is going to have the highest boiling point?

A. 1.5 m NaCl
B. 1.5 m AgCl
C. 2.0 m C6H12O6
D. 2.0 m CaCl2
E. 1.0 m Al2(SO4)3

I chose D (which was right) because in a solution, the more solute particles there is the higher the boiling point (this is what I learnt). Could someone tell me if this is the correct logic?

Thanks!
