The correct answer is D. Centrifuge.

A centrifuge is a machine that uses centrifugal force to separate materials. It works by spinning a container around a central axis. The centrifugal force pushes the materials towards the outside of the container, with the heavier materials moving further out than the lighter materials. This can be used to separate different liquids, or to separate solids from liquids.
