Explanation:
Gas is the state of mater which changing its shape and volume according to the volume and shape of container.
Properties of gas:
Molecule of gases randomly move everywhere and occupy all available space.
Gases don't have definite volume and shape and take the shape and volume of container in which it present.
Their densities are very low as compared to the liquid and solids.
Gas molecules are at long distance from each other therefore by applying pressure gases can be compressed.
The very weak inter molecular forces are present between gas molecules.

The correct classification of the statement is all compounds.
Explanation:
- All matter is defined as something that entirely has weight and occupies some sought of space. That's why it can't be used to describe the above statement.
- All elements are defined as substances that have an equal number of protons. The atoms in an element contain an exact atomic number.
- All compounds can be defined as a formation that takes place when a variety of atoms are chemically combined. Hence, this explains the answer above.
- All pure substances mean that the substance is not mixed with anything at all. It's just by itself.
