Strategy:
 Freezing point (FP) is inversely proportional to the total number of particles (). Ethanol is a non-electrolyte (), so it serves as the reference point at 0.10 M.

Step 1: Establish the reference concentration
Reference: .

Step 2: Evaluate each electrolyte
Any solution with  will have a lower freezing point.
- (i) : Total ions () = 5. . (Lower)
- (ii) : Total ions () = 3. . (Lower)
- (iii) : Total ions () = 2. . (Lower)
- (iv) : Total ions () = 4. . (Lower)
