Some students investigate the properties of four objects using a hand lens, a magnet, and a beaker containing water. Their observations are recorded in the table. Which statement identifies a property that could be used to classify these objects into two different groups?

• Density can be used to separate objects that sink in water from objects that do not.

• Magnetism can be used to separate objects that are attracted by a magnet from objects that are not.

• Solubility can be used to separate objects that dissolve in water from objects that do not.

• Physical state can be used to separate objects that are solids from objects that are not.
