Best answer

Answer: 3. Distillation

Key idea: the metal liquid at room temperature is mercury, which is volatile with a low boiling point (630 K).

Distillation separates the volatile metal from non-volatile impurities and gives very pure mercury. Zone refining and chromatography are used for solids; electrolytic refining is for metals in solution/molten form.
