Solution

The correct option is D [FeCl4]2
In [Co(CN)6]4, the Co2+(d7) ion undergoes sp3d2 hybridization to form outer orbital complex with 3 unpaired electrons.
In [Cr(H2O)6]3+, the Cr3+(d3) ion undergoes sp3d2 hybridization to form outer orbital complex with 3 unpaired electrons.
In [FeCl4]2, the Fe2+(d6) ion undergoes sp3 hybridization with 4 unpaired electrons.
In [Fe(H2O)6]3+, the Fe3+(d6) ion undergoes sp3d2 hybridization to form outer orbital complex with 5 unpaired electrons.
