Density is the mass of a material divided by its volume. Which option correctly names this property?

Explanation:
Density measures how much matter is in a given volume. It is defined as mass divided by volume, so it tells you how heavy a material is for its size. Among the terms listed, the one that names this exact property is density, because it directly describes the mass-per-volume relationship. Hardness describes resistance to scratching or indentation, viscosity describes a liquid’s resistance to flow, and elasticity describes how well a material returns to its original shape after deformation. These describe other behaviors, not how much mass sits in each unit of volume.
