The correct answer is D) centrifuge the mixture because the substance with the highter density will be pulled to the bottom

When things spin around, like a centrifuge, the centripetal force draws things towards the middle. If you make it a bit like a spiral and put it sideways, then the denser thing will go to the bottom while the less dense ones will remain on the outside.
