Which of the following complex ion is not expected to absorb visible light?

A complex ion does not absorb visible light if it has no $d-d$ transition possible. This usually happens in $d^0$, $d^{10}$, or sometimes in specific low-spin configurations where all levels are filled or symmetrical.$[{\text{Ni(CN)}}_4{]}^{2-}$ is a square planar complex of ${\text{Ni}}^{2+}(d^8)$ with strong-field ${\text{CN}}^{-}$ ligands. It is diamagnetic (all electrons paired). Due to its specific energy level splitting and lack of unpaired electrons, it often appears colourless or absorbs outside the visible range.
