using a magnet


B.
distillation


C.
evaporation


D.
observing different densities

Answer 1

A. using a magnet
Your best choice is a magnet,
Magnets attract various metals and alloys, including iron and cobalt, but not including aluminium, so if you put a magnet above a mixture of iron and aluminium filings, it'll pick the iron filings up and stick to them, but it won't do that to the aluminium, so when you take the magnet away it'll drag the iron with it but not the aluminium.
