Text Solution
Verified by ExpertsThe correct answer is:
D
Potassium permanganate 
forms dark purple colored crystals because it absorbs light in the visible range of the electromagnetic spectrum.
As a ligand-to-metal charge transfer takes place between the oxygen's p - orbitals and the empty d-orbitals on the metal. This charge transfer takes place when a photon of light is absorbed, which leads to the purple color of the compound/ion
