Solution

The correct option is C Hexaaminechromium (III) ion
(A)[Ni(CN)4]2
Ni2+ has electronic configuration: 3d84s0
This complex is diamagnetic because due to the presence of a strong field ligand all electrons gets paired up.
(B)[Zn(NH3)4]2+ is diamagnetic in nature.
Zn2+ has electronic configuration: 3d104s0
(C)[Cr(NH3)6]3+ is paramagnetic due to the presence of unpaired eletrons.
Cr3+ has electronic configuration: 3d34s0
(D)[Ag(NH3)2]+ is diamagnetic due to absence of unpaired electron in it.
Ag+ has electronic configuration: 4d105s0
