A) glucose
B) Water
C) Both [a] & [b]
D) None of these
Correct Answer: B
Solution :
Key Idea: The freezing point of a liquid is that temperature at which the liquid and its solid state exists in equilibrium with each other and have some vapour pressure. Due to lower vapour pressure of solution, solid form of solution separates out at lower temperature. The decrease in temperature is called depression in freezing point. \[\therefore \] When solution containing glucose is allowed to freeze then crystal of water will be separated first.
