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 allwavelengths in the visible region.(C) Since Zn2+ is a d10 ion, it does not absorb visible light even though the “dorbital” splittings are correct for absorbing visible wavelengths.(D) Zn2+ is not a transition metal ion.(E) None of these is correct.
