    Hello!

    B) The iron filling would be easiest to separate, and using a magnet would be the best method.

    This separation would be based on the magnetic properties of Iron. This is called Ferromagnetism. The magnetic field produced by the magnet will attract the iron filling, which is a ferromagnetic material, unlike sand or salt. All dipolar moments of the electrons of iron align towards the magnetic field and allow for easy separation of the iron filling.

    Have a nice day!
