(B) The spin-only magnetic moment is calculated using the formula $\mu = \sqrt{n(n+2)} \ B.M.$, where $n$ is the number of unpaired electrons.$A$. $Ti^{3+}$ $(3d^1)$: $n = 1$, $\mu = \sqrt{1(1+2)} = \sqrt{3} \approx 1.73 \ B.M.$ $(III)$$B$. $V^{2+}$ $(3d^3)$: $n = 3$, $\mu = \sqrt{3(3+2)} = \sqrt{15} \approx 3.87 \ B.M.$ $(I)$$C$. $Ni^{2+}$ $(3d^8)$: $n = 2$, $\mu = \sqrt{2(2+2)} = \sqrt{8} \approx 2.84 \ B.M.$ $(IV)$$D$. $Sc^{3+}$ $(3d^0)$: $n = 0$, $\mu = \sqrt{0(0+2)} = 0.00 \ B.M.$ $(II)$Therefore, the correct matching is $A-III, B-I, C-IV, D-II$.
