| Conducts electricity when solid | Conducts electricity When molten | At room tempreture and pressure | Can be bent or shaped | |
| Option A | Yes | Yes | Solid | Yes |
| Option B | No | No | Solid | No |
| Option C | No | Yes | Solid | No |
| Option D | No | No | Solid | Yes |
Sodium chloride is an ionic compound. In solid state it forms a crystal lattice with strong electrostatic forces of attraction between the oppositiely charged $Na ^{+}$ and $Cl ^{-}$ ions. Thus, ions are not free to move in solid state which makes the solid sodium chloride a bad conductor of electricity, while in the molten state ions are free to move and thus, it is able to conduct the electricity.
Also, due to the presence of strong electrostatic forces of attraction, Sodium chloride cannot be bent or shaped.
