Choosing a separation method

A solid sample of iodine and sand is given. Iodine sublimes easily when heated, but sand does not sublime and is insoluble in water. Which two separation techniques should be used, in the correct order, to obtain pure solid iodine and pure sand?

Sublimation, then filtration
Filtration, then sublimation
Evaporation to dryness, then sublimation
Crystallisation, then filtration
