1. The central metal is Ruthenium (Ru). 2. The complex has two NH3 (diammine) ligands and one en (ethylenediamine) ligand. 3. The ligands are listed in alphabetical order, so NH3 comes before en. 4. The NH3 ligands are named together as diammine. 5. The anionic ligand bound to Ru is named first, which is NH₃ and is called pyridine-2-sulfonamide (NHSO2C5H4N). 6. The anion bound to the metal is named last, which is nitrate (NO3). 7. The coordination number of Ru is 6 (two NH3 ligands, one en ligand, one pyridine-2-sulfonamide ligand, and two nitrate ligands), so the oxidation state of Ru is +2. Therefore, the systematic name is diammine(ethylenediamine)ruthenium(II) nitrate, which corresponds to choice C.
