35. The complex ions of Zn²⁺ are all colorless. The most likely explanation for this is:
(A) Zn²⁺ is paramagnetic.
(B) Zn²⁺ exhibits “d orbital” splittings in its complexes such that they absorb all wavelengths in the visible region.
(C) Since Zn²⁺ is a d¹⁰ ion, it does not absorb visible light even though the “d orbital” splittings are correct for absorbing visible wavelengths.
(D) Zn²⁺ is not a transition metal ion.
(E) None of these is correct.
