Considering `H_(2)O` as a weak field ligand, which of the following aqua complexes will have the minimum spin only magnetic moment ? [ N i ( H 2 O ) 6 ] 2 + [ C o ( H 2 O ) 6 ] 2 + [ F e ( H 2 O ) 6 ] 2 + [ M n ( H 2 O ) 6 ] 2 +

A

`[Ni(H_(2)O)_(6)]^(2+)`

B

`[Co(H_(2)O)_(6)]^(2+)`

C

`[Fe(H_(2)O)_(6)]^(2+)`

D

`[Mn(H_(2)O)_(6)]^(2+)`
