The oxidation states of the metals in the complexes along with the electronic configuration are given :
(a) `Cr^(3+) : 3d^(3)` configuration , unpaired electrons = 3
(b) `Fe^(2+) : 3d^(6)` configuration , unpaired electrons = 4
(c) `Zn^(2+) : 3d^(10)` configuration , unpaired electrons = 0
The complex (b) with maximum number of unpaired electrons has the highesht magnetic moment. therefore, (b0 is the correct answer
