The correct statement explaining why physical properties of a substance can be used to separate mixtures is:

When substances are mixed together, they retain their physical properties.

This means that the different components of a mixture maintain their individual characteristics (such as color, size, shape, and boiling point), which allows for processes like filtration, distillation, or chromatography to be used to separate them based on these physical properties.
