CaCl2, NaCl, and sugar derived from beet juice are all commonly used in winter to melt ice on streets. At the same molality, which of these would be most effective at this task and why?

delta T =i*K*molality
So look at this sensibly.
m is the same for all, K is the same for all, so delta T changes only with i, the van't Hoff factor and that is the number of particles per mole of the material.
CaCl2 has ? when dissolved in water.
NaCl has ?when dissolved in water
Suar (C12H22O11) has ? when dissolved in water.
Your answr is what?
