The correct order of matching of complex compound in column I with the properties in column II:
`{:(,"Column I",,"Column II",),((A),[Cr(NH_(3))_(6)]^(3+),(P),"Tetrahedral and paaramagnetic",),((B),[Co(CN)_(6)]^(3-),(Q),"Octahedral and diamagnetic",),((C ),[Ni(CN)_(4)]^(2-),(R ),"Octahedral and paramagnetic",),((D),[Ni(Cl)_(4)]^(2-),(S),"Square planar and diamagnetic",):}`

Options

A. `A-R, B-Q, C-P, d-S`
B. `A-Q, B-R, C-P, D-S`
C. `A-R, B-Q, C-S, D-P`
D. `A-Q, B-R, C-S, D-P`

Answer

C

Explanation

`[Cr(NH_(3))_(6)]^(3+) - (d^(3)) - d^(2)sp^(3)` hybridised & paramagnetic
`[C0(CN)_(6)]^(3-) - (d^(6)) - d^(2)sp^(3)` hybridised (`CN^(+)` is a strong field ligand)
