When is steam distillation applied?

Given below are two statements:
Statement $I$: $A$ mixture of $C_{12}H_{22}O_{11}$ (sugar) and $NaCl$ can be separated by dissolving sugar in alcohol, due to differential solubility.
Statement $II$: Rose essence from rose petals is separated by steam distillation due to its high volatility and insolubility in $H_2O$.

Which property should a solvent used in crystallization possess?

What is the difference between distillation,distillation under reduced pressure,and steam distillation?

Which method is used to separate a mixture of aniline and water?

Fill in the Blanks :
