Answer:
The correct answer is d) Barred Germany from maintaining an army.
Step-by-step explanation:
The First World War had its beginnings on July 28, 1914, ending on November 11, 1918, after that period the countries involved met to sign a peace treaty, which was known as the Treaty of Versailles.
The countries involved were in disagreements to be able to sign the peace agreement until finally, after a few months, the Versailles Treaty was signed and launched. The treaty stipulated that Germany should pay for damages caused by the war since they considered it to be the country responsible for it. They also established military clauses where Germany was restricted to having a General Staff of the Army, not manufacturing war products, suspending compulsory military service, and reducing the men who were part of the army.
Germany had to accept the Treaty of Versailles but was not satisfied with it, so it was one of the causes that Adolf Hitler used to start the Second World War.
