Solution

The correct option is C
Specific gravity

The ratio of the density of a substance to the density of water at $4^{\circ} C$ is usually referred as specific gravity. It is a dimensionless quantity. If the specific gravity is greater than $1$ it will sink in water and less than $1$ it will float in water.
