(NH₄)₃PO₄ has  the lowest freezing point.

Solution properties are the properties of a solution that don't depend on the type of solute but only on the concentration of the solute.

Solution properties of electrolyte solutions differ from non-electrolyte solutions because electrolyte solutions contain a greater number of particles because electrolytes break down into ions. So the Solution properties of electrolytes is greater than non-electrolytes.

The term is used in the Solution properties

that is, the number of moles of solute in 1 kg of solvent

Solutions from volatile substances have a higher boiling point and lower freezing points than the solvent

ΔTb = Tb solution - Tb solvent

ΔTb = boiling point elevation

Kb = molal boiling point increase

Kf = molal freezing point constant

m = molal solution

For electrolyte solutions there is a van't Hoff factor = i

i = 1 + (n-1) α

n = number of ions from the electrolyte

α = degree of ionization, strong electrolyte α = 1

so the freezing point formula becomes:

All solutions in the problem have molal concentration (0.075 m) and the same solvent -> assuming water (The same ) so that what affects the value of is the value of i

Assuming the degree of electrolyte ionization α= 1, the magnitude i is determined by the number of ions produced by the electrolyte (n)

KNO₂ ---> K⁺ + NO₂⁻ → 2 ions

LiCN ---> Li⁺+ CN⁻ → 2 ions

(NH₄)₃PO₄---> 3 NH₄ + + PO₄ ³⁻ → 4 ions

NaI ---> Na⁺ + I⁻ → 2 ions

NaBrO₄ ---> Na⁺ + BrO₄⁻ → 2 ions

(NH₄)₃PO₄ has the highest number of ions, so it has the highest and the lowest freezing point.
