FeS is purely ionic compound.It's ionic because there is no bond formed, and the atoms are ionized in water
Where rest of all compound have covalent bond between atom and they are not ionise in water
Hence option (B) FeS is the correct answer

Identify the characteristics of ionic electrolytes Question Which of the following occurs when an ionic compound dissolves in a polar solvent such as water? Select all that apply: The water molecules chemically react with the ions. The disorder of the ionic salt is decreased. The water molecules attract both the anions and cations in the ionic salt. The ions become solvated water molecules, which reduces the electrostatic attractions between the ions.
