The correct option is C.
- The ions which have half-filled, full-filled or vacant d orbitals can't undergo d-d transition and remain colourless.
- The electronic configuration of is
Thus it contains filled d orbital and remains colourless.
- The electronic configuration of is
- Thus it contains filled d orbital and remains colourless.
- The electronic configuration of is
- Thus it contains one electron in d orbital and undergoes a d-d transition and give colour.
- The electronic configuration of is
- Thus it contains vacant d orbital and remains colourless.
