Hi!
The answer would be solid.
Explanation:
There are three essential states of matter:
In a solid, the particles are seen to be in a strict orderly arrangement, and only show restricted movement about their place.
In a liquid, the particles do not have a particular arrangement, and have a more free movement with respect to solid, and can change their position through the sample.
In a gas, the particles are most widely spaced, and have no defined arrangement. They have the most free movement of the other two states.
See the attached picture for a clearer idea.
Hope this helps!
