(A) $V^{4+}$ $(3d^1)$,$Ti^{3+}$ $(3d^1)$,and $Ni^{2+}$ $(3d^8)$ have unpaired electrons in their $d$-subshell. Therefore,these ions show $d-d$ transition and exhibit characteristic colours.$Ti^{4+}$ $(3d^0)$ does not have any unpaired electrons,therefore it is colourless.Matching the ions with their colours:$A. V^{4+}$: $IV. Blue$$B. Ti^{3+}$: $II. Purple$$C. Ti^{4+}$: $I. Colourless$$D. Ni^{2+}$: $III. Green$Thus,the correct matching is $A-IV, B-II, C-I, D-III$.
