Which of the following complexes are diamagnetic? [Mn(CN)6]4- , [Zn(NH3)4]2+, [Fe(CN)6]4-, [FeF6]3-

[Zn(NH3)4]2+ [Zn(NH3)4]2+ and [FeF6]3- [Zn(NH3)4]2+ and [Fe(CN)6]4- [Mn(CN)6]4- , [Zn(NH3)4]2+, [Fe(CN)6]4-

[Zn(NH3)4]2+ and [Fe(CN)6]4-

[Zn(NH3)4]2+ and [Fe(CN)6]4-  These are diamagnetic because as both of them have all electrons paired in d orbital.
