Solution

The correct option is C
L → M charge transfer transition

L→M charge transfer transition

In [MnO₄]¯, the electronic configuration of Mn is [Ar]3d⁰. As there are no d electrons, the colour is not due to a d-d transition of electrons. In this case, the electron transition takes place from the orbital of the ligand to the empty d orbital of Mn.
