Answer:
D) freezing point depression
Explanation:
The correct option would be option D.
Calcium chloride has the ability to lower the freezing point of water due to its capacity to form brine when in contact with ice or snow. The hygroscopic nature of the compound enables it to extract moisture from the surrounding to form brine. The brine thus enables it to quickly melt the ice/snow.
The correct answer is freezing point depression.
