Respuesta :

abudi

D. because sodium chloride is an ion

first of all , sodium chloride is salt and  we all know that it is not malleable.

sodium chloride is an ion which do conduct electricity but not when they are solid.....they only do so when they are molten or aqueous ( dissolved in water )

sodium chloride is an ion. ions have high melting points.

D is true because as i have mentioned above , ions will conduct electricity when dissolved in water / aqueous or molten.......... HOPE IT HELPED !!!!!!
