D Correct answer
Explanation

Salt lowers the freezing point of water through freezing point depression, causing ice to melt at temperatures below 0°C. This colligative property depends on the number of solute particles, not their identity. Acids like H2SO4 and HCl would also lower freezing point but are corrosive and not used for de-icing.
