Answer
vacuum
Explanation
The question is seeking the definition for a space that has literally no matter. This can be described with three possibilities according to the question: a gas, a vacuum, solid, or liquid.1. "Gas" refers to a state of matter that has no fixed shape and can expand or contract to fill any available space, so this is not correct as it still contains matter.2. "Solid" is typically characterized by structural rigidity and resistance to changes of shape or volume. So it has matter, this option isn't valid.3. "Liquid" is a nearly incompressible fluid that conforms to the shape of its container but retains a (nearly) constant volume irrespective of pressure, that still contains matter, it's not valid too.4. A "Vacuum" is a space void of matter, meaning there are no atoms, molecules, or particles in such a space. From these definitions, it is clear that a space that contains no matter in it is classified as a vacuum.
