  2. B[ Pd ( PPh ₃ )₂( NCS )₂ ] and [ Pd ( PPh ₃ )₂( SCN )₂ ]
  3. C[ CO ( NH ₃ )₅ NO ₃ ] SO ₄ and [ CO ( NH ₃ )₅ SO ₄ ] NO ₃
  4. D[ PtCl ₂ ( NH ₃ )₄ ] Br and [ PtBr ₂ ( NH ₃ )₄ ] Cl ₂

Correct answer

B. [ Pd ( PPh ₃ )₂( NCS )₂ ] and [ Pd ( PPh ₃ )₂( SCN )₂ ]

Step-by-step solution

NCS is ambidentate ligand and it can be linked through N (or) S
