Answer
Correct option: B.
Vacum distillation
b
The liquids which decompose at its boiling point can be purified by vacuum distillation. Glycerol decomposes at its boiling point $(563\, K$ ). It can be distilled by vacuum distillation without decomposition at $453 \,K$ and under $12\, mm \,Hg$ pressure.
