Solution

The correct option is B Freezing point is raised
Copper sulphate in ammonia solution form a complex which will lead to decrease the number of particles in solution. So, van`t hoff factor will decrease. Depression in freezing point and elevation in boiling point are directly proportional to the van`t hoff factor. Decreases in number of particles causes the increase in freezing point and decrease in the boiling point. So, the correct option is (B).
