Unlike solid and liquid state, molecules in gaseous state show random motion. That is the reason, gases take the shape of container and spread quickly in space. The random motion of molecules in the gaseous state is due to high kinetic energy in molecules. They have weak intermolecular interactions between them.
D. "The collision between the gases is perfectly inelastic" is not accurate. 
In an ideal gas model, collisions between gas molecules are considered perfectly elastic, meaning kinetic energy is conserved.
