Dear student
Please find the solution to the asked query:
CuF2 will be coloured due to the presence of unpaired d electron in Cu2+.Cu exists in the +2 state in this compound
So, when Cu is 3d104s1, Cu2+ will be 3d9, thus a unpaired electron is present in the compound.
It can thus undergo d-d transition and show coloration.
Hence option (ii) is correct
The remaining compounds do not have unpaired electrons.
