No these are the first level divisions of Yugoslavia. Kosovo had autonomous status, but was a part of Serbia and not at the same level as the others shown here. Vojvodina was in the same boat.
I will update the quiz. this is my source for the Bosnian cities. I was confused what the dashed lines on "cities" such as Novi Grad meant so I assumed they were suburbs not included in Sarajevo's population. Thank you.
