Assuming that this question is comparing two situations, only water as situation 1 and water + calcium chloride as situation 2. In this case, we will have the salt interacting with water in something called Colligative properties, which depending on the concentration of the solute, it will cause changes in physical state change of the solution. Salts in water tend to cause two things, regarding physical change, they raise the boiling point and lower the freezing point. Which is the case for this question, we have a solution with salt + water, therefore we will have a higher boiling point and a lower freezing point, number 3
