Answer

B

Explanation

The catoin is named before the anion. When writing the name of a complex entity, the ligands are quoted in alphabetical order, regardless of their charge (followed by the metal). The oxidation state of the central metal atom/ion is shown by a Roman unmeral in brackets immediately following its name. Complex positive ions and netural molecules have no special endings but complex negative ions end in - ate.
