Solution

The correct option is D Sc3+
Those ion which has unpaired electrons in d orbital can exhibit colour due to d-d transition.
Those with fully filled or empty d orbitals are colourless.
In Sc3+:18[Ar]3d0
there are no electrons in 3d and the other orbitals all are completely filled, and hence it is colourless.
