Solution

The correct option is A True
The statement is true.
Ice on hills side road is melted by spraying salt which decreases the melting point of ice. When salt is added there is a lower concentration of water molecules in the liquid to come back and form ice, so the freezing slows, and the melting rate also decreases. Thus the overall ice melts.
