I don't know the answer to this one, but it says "based on the name". Well, metals - copper and chromium tend to bond ionically. You get chlorine ions and sulfate ions. If there's such a thing as a carbonate ion (C03) then I'd go for c. The name dinitrogen pentoxide N205 reminds me of another name for water as "dihydrogen oxide" H20. I think that water molecules are covalent, so I'd guess at c.
