Solution

The correct option is C [Fe(CN)6]4
In [Fe(CN)6]3, Fe is in +3 state.
x+6(1)=3
x=+3
In [Fe(CN)6]4, Fe is in +2 state.
Orbitals of Fe2+ is
3d 4s 4p 4d

Orbitals in [Fe(CN)6]4 is:
d2sp2

Orbitals in Fe+3 is:
3d 4s 4p
Orbitals in [Fe(CN)6]3 is:
d2sp2
In [Fe(CN)6]4, there is no lone pair. So it is a diamagnetic ion.
