• A. is lowered
• B. is raised
• C. remains the same
• D. becomes infinte

Answer 1

The correct option is A is lowered

When salt is added to ice then the melting point is lowered.

Chemically, it is due to interaction between the water molecules as well as salt molecules which pushes the melting point. This is the fact why salt is use to melt ice on roads during winter.
