Solution

The correct option is D iii and iv
Primary valency: This corresponds to oxidation state of the metal ion. This is also called principal ionisable or ionic valency. It is satisfied by negative ions and its attachment with the central metal ion.
Compound with unpaired electron shows colour and magnetism.
But as Zn+2 don't have any unpaired electron so it is colourless.
MnCl2 exhibits pink color in aqueous solution.
Magnetic nature depends on the type of ligand and not the element.
