Which is a physical property of ionic compounds in their solid state? a. low boiling point b. high melting point c. weak attractive forces between ions d. good conductor of electricity?

Ionic bonding is the strongest among all chemical bonds. Because the force that bonds the atoms is strong, it will require greater energy to break the bond. Thus, compounds with ionic bond is expected to have a high melting and boiling point. 

Iwould you figure it out but you don't have a picture or in your question as to what the physical property you're looking for is
