Answer:
c) pay reparations
Step-by-step explanation:
the treaty of the Versailles, or the peace treaty, required Germany to pay a reparation of $33 billion to cover the civilian damage caused in the war. They were also made to admit that the entirety of the war was their fault - even though Germany did not start the war - as part of Article 2.3.1, which was known as the 'war guilt cause', blaming Germany for it all and causing humiliation for the country and their military.
