This is the solid state.
The answer you are probably looking for is 1. water in a freezer. Particles in a solid have fixed positions. Rigid is perhaps a misleading word to use, however, as the particles are not still but vibrating around their fixed positions.
It is in a solid state.
No. According to the Kinetic Particle Theory, the particles in a solid are fixed very close together in fixed positions. They are not free to move and can only vibrate about their fixed positions, due to the strong attractive forces between them. This explains why solids have fixed shapes.
Solid !
A SOLID. They have a fixed volume mass and shape because the particles are so closely packed together.
Particles are held (relatively) rigidly in place in a solid. They are held rigidly in place in a solid at absolute zero.

Gases.
There are three states of matter, solid, liquid and gas. The state of matter wherein particles are fixed in a rigid structure is solid.
It is in a solid state.
Solids: Atoms are not free to move about; they vibrate about their fixed positions Liquids: The particles are free to move about by sliding over each other Gases: The particles more about randomly at high speeds

In a solid the particles are close together and in fixed positions In a liquid the particles are still really close together but can move around past each other In a gas the particles are free to move and far apart During a state change the particles in the substance will change from being in one of the above to another
The particles are no longer fixed by the forces keeping it a liquid
the particles in the solid vibrate so fast that they break free from their fixed positions
the particles in the liquid move so slowly that they begin to take on their fixed positions
Gas particles are apart from each other, thus is has no fixed positions. As it has no fixed positions, it has no definite shape. Gas particles are also moving in distances away from each other, thus gases may be compressed, giving in an indefinite volume.
