Glucose does not dissociate. So it has the minimum number of particles, and therefore, it shows minimum depression in freezing point. So it has the maximum freezing point.

Correct Answer – D
Glucose, being non-electrolyte, gives minimum no. of particles and hence minimum `Delta T_(f)` or maximum F. pt.

Correct Answer – D
