The correct answer is:

CHECK THE SOLUTION.

(a, b, c, d)

[Ag(NH3)2]–

Ag( Ι ) → 4d10 5s0

NiCl42– , VO43– and MnO4– have tetrahedral geometries.

Ni2+ → 3d8

[Cu(NH3)4]2+, [Pt(NH3)4]2+ and [Ni(CN)4]2– have square planar geometries.

[Cu(NH3)4]2+

Pt2+, [Xe]4f14 5d8

[PT(NH3)4]2+

dsp2 hybrid orbitals

similarly the hybridisation scheme for [ni(cn)4]2– (cn– is a strong field ligand) is as shown in figure.

NI2+,[AR]3D8

[NI(CN)4]2–

DSP2 HYBRID ORBITALS

[Fe(co)5 ] is diamagnetic and has dsp3 hybridisation. so it has trigonal bipyramidal geometry.
