Step-by-step solution

In option A, the complex is [ CoBr ₂( en )₂ ] Cl . The IUPAC name is dibromidobis(ethane-1,2-diamine)cobalt(III) chloride. The prefix 'di' is used for simple ligands, but for ligands like ethane-1,2-diamine which already contain a numerical prefix, 'bis' should be used. Thus, the name given in the table is incorrect. In option B, the complex is Na [ PtBrCl ( NO ₂)( NH ₃) ] . The ligands are ammine, bromido, chlorido, and nitrito-N. Alphabetical order is ammine, bromido, chlorido, nitrito-N. The metal is in the anio
