Vedclass · Answer

(B) Ions exhibit colour in aqueous solution due to the presence of unpaired electrons in their $d$-orbitals,which allow for $d-d$ transitions.Electronic configurations:$La^{3+} (Z=57): [Xe] 4f^0 5d^0$ (No unpaired electrons).$Ti^{3+} (Z=22): [Ar] 3d^1$ (One unpaired electron).$Lu^{3+} (Z=71): [Xe] 4f^{14}$ (No unpaired electrons).$Sc^{3+} (Z=21): [Ar] 3d^0$ (No unpaired electrons).Since $Ti^{3+}$ has one unpaired electron,it will exhibit colour in aqueous solution.
