What are the defining characteristics of matter

Explanation:

Matter is defined as the substance that has mass and occupies space. So basically a physical property of a substance helps us to determine whether a substance is matter or not.

As a property that does not bring any change in chemical composition of a substance are known as physical properties.

For example, shape, size, mass, volume, density, etc of a substance are all physical properties.

Thus, we can conclude that the defining characteristics of matter are physical properties.

your picture is not part of the scientific method.

specific gravity is the density of a substance divided by the density of water. since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density

so "c" is the answer
