Detailed Solution
(a) Valence shell electron configuration of ZnII is 3d104s0. So has no unpaired electrons.(b) Valence shell electron configuration of MnIV is 3d34s0. So has 3 unpaired electrons.(c) Valence shell electron configuration of FeII is 3d64s0. So has 4 unpaired electrons.(d) Valence shell electron configuration of TiIII is 3d14s0. So has one unpaired electrons.So, Fe(Il) has highest value of magnetic moment as given by B. M.
