Answer:B is an ionic compound
Explanation:This is because when we look at the properties of ionic compounds, we see that the form crystals just like salt(sodium chloride), they dissolve in water, have a high boiling and melting point, are hard due to the strong intermolecular forces between atoms and conduct electricity (only molten or in solution form)
Explanation:
option A skeleton system is correct option
