Which physical method can separate a mixture of steel ball bearings and marbles? boiling evaporation filtration sorting sorting i took the test

sorting.

Justification:

1) Boiling is used  to separate two or more liquids with different boilng poins.. By heating the liquid with lower boiling point will evaporate first and then substances get separated.

2) Evaporation: similar to boiling, but this permits to separate all the liquid phase and leave the solid solute.

3) Filtration; is used to separate small yet visible particles from a liquid by passing the mixture by a suitable mesh.

4) Sorting: It is based on the ability to identify the constituents of the mixture visually and separate them manually or with a device that can tell the difference visually. This is the case of the bearings and the marbles.

The answer for this question is d. none of these

Ithink is a because if say increased in electronegativity
