I believe the answer is: B. i (local) and ii (national)
The treaty of Versailles was not a good peace treaty because even though it brought world war I to an end, it is a big factor in starting world war II. It put the Germans in Great debt and completely ruined their economy. Many Germans were very mad about this. The treaty also said that they are the ones to blaim for the whole war. Things like this is what drove people like Adolf Hitler to take charge and try and save Germany, even if it meant a whole other war and passing the blaim to a whole other race.
