In an amorphous solid, the particle arrangement on both a macroscopic and microscopic scale has no periodicity, it is literally amorphous. On a crystalline solid, the particles arrangement is neat and ordered. There is a periodicity to the particles.
crystalline solids
Solid
The answer for the worksheet you are most likely doing; is I. Solid.
crystals differ from solid matter from the fact that there is definite arrangement of the various constituting particles in the three dimensiomal space i.e, in the space lattice and there exist electrostatic forces of attraction between the various particles but in case of solids there can be definite arrangement of particles but the forces of interaction are generally metallic, covalent or any other
Amorphous solids can have a random arrangement of particles.

In an amorphous solid, the particle arrangement on both a macroscopic and microscopic scale has no periodicity, it is literally amorphous. On a crystalline solid, the particles arrangement is neat and ordered. There is a periodicity to the particles.
In a liquid, the particles are free to move around; in a solid, they have a fixed position. In a solid, the particles may have a regular structure (i.e., a crystal), or the structure may be irregular.
Most solids do not have an orderly arrangement of particles: these are non-crystalline solids.
Arrangement of particles determind the phase
the arrangement of particles in a pancake are that when you prepare the pancake with the ingredients it turns into a liquid and then when you cook it change into a solid

Gasses, or plasmas.
Crystal
It varies with the compound.
