Explanation:

Ionic compounds are formed by the transfer of electrons from a metal to a non - metal, resulting in the formation of ions. These ions are held together by strong electrostatic forces (ionic bonds).

• Crystalline structure: Ionic compounds have a regular, repeating three - dimensional arrangement of ions, which gives them a crystalline structure.
• Solid at room temperature: Due to the strong ionic bonds, ionic compounds are usually solid at room temperature. The ions are fixed in their positions in the crystal lattice.
• High melting point: A large amount of energy is required to break the strong ionic bonds and convert the solid ionic compound into a liquid. So, they have high melting points.

Ionic compounds are not liquid at room temperature (eliminating the "liquid at room temperature" option) and do not have low boiling points (eliminating the "low boiling point" option) as the ionic bonds are strong and require a significant amount of energy to overcome, which is reflected in high boiling points as well.

Answer:

crystalline, solid at room temperature, high melting point
