I believe the 3rd and 4th one are right, since Wilson promoted a policy that goes kinda like "a nation, a country"; he was opposed to empire, which included Germany and Turkey (ottoman empire), but mostly the Austro-Hungarian empire that got dissolved into plenty of smaller nations. He also spend a lot of time during the peace-negociation to set up the League of Nation (UN ancestor) in order to preserve peace throughout the world. So I guess that 3 is kinda right, and so is 4. BTW sorry if I made some grammar error, my native language us french!
