Which best describes the function of a centrifuge? -to separate the solute from solvent -to separate the dissolved part of a solution into layers -to separate a mixture by heating it for a long period of time -to separate the undissolved particles of a mixture into layers

The answer is D. to separate the undissolved particles of a mixture into layers

A laboratory centrifuge is used for the separation of fluids, gas or liquid, based on density. The centrifugal force created by the spinning the vessel containing the material pushes the materials outside of the vessel, thus, separating dissolved particles from undissolved particles.

Hope this helps :)
