(B) To find the magnetic moment $(\mu)$,we use the formula $\mu = \sqrt{n(n+2)} \ BM$,where $n$ is the number of unpaired electrons.$I. [FeF_6]^{3-}$: $Fe^{3+}$ is $3d^5$. $F^-$ is a weak field ligand,so $n=5$. $\mu = \sqrt{5(5+2)} = \sqrt{35} \approx 5.93 \ BM$ $(B)$.$II. [Ti(H_2O)_6]^{3+}$: $Ti^{3+}$ is $3d^1$. $n=1$. $\mu = \sqrt{1(1+2)} = \sqrt{3} \approx 1.73 \ BM$ $(A)$.$III. [Cr(NH_3)_6]^{3+}$: $Cr^{3+}$ is $3d^3$. $n=3$. $\mu = \sqrt{3(3+2)} = \sqrt{15} \approx 3.88 \ BM$ $(E)$.$IV. [Ni(H_2O)_6]^{2+}$: $Ni^{2+}$ is $3d^8$. $n=2$. $\mu = \sqrt{2(2+2)} = \sqrt{8} \approx 2.83 \ BM$ $(D)$.$V. [Fe(CN)_6]^{4-}$: $Fe^{2+}$ is $3d^6$. $CN^-$ is a strong field ligand,causing pairing,so $n=0$. $\mu = 0.00 \ BM$ $(C)$.Thus,the correct matching is $I-B, II-A, III-E, IV-D, V-C$.
