Which of the following statements correctly describes a characteristic physical property of ionic compounds?

A) They conduct electricity efficiently in the solid state due to the presence of freely moving valence electrons.

B) They typically exhibit low melting and boiling points due to weak intermolecular forces between discrete molecules.

C) They are malleable and ductile because ionic crystal planes can easily slide past one another without repelling.

D) They do not conduct electricity in the solid state, but conduct electric current when melted or dissolved in water.
