A. Salt
B. Chlorine
C. Carbon dioxide
D. Water
Check Answer
The correct answer is A) Salt.
A common material used to melt ice on roads in cold countries is salt, specifically rock salt or sodium chloride. When salt is spread on ice, it can lower the freezing point of the water, causing it to melt. This can help to make roads safer to travel on during winter. Other materials that may be used to melt ice on roads include calcium chloride, magnesium chloride, and potassium chloride. Carbon dioxide and water are not typically used for this purpose.
