Remember Cedric. Remember, if the time should come when you have to make a choice between what is right and what is easy, remember what happened to a boy who was good, and kind, and brave, because he strayed across the path of Lord Voldemort. Remember Cedric Diggory.

note that H2O is a weak ligand so it cant pair the ens. Also all the metals are in their +2 states so we need to find the metal that has the min no of unpaired ens in +2 state without pairing.
