Final answer:
In the Treaty of Versailles, the Allies imposed harsh conditions on Germany, including reparations, disarmament, and territorial losses. Option D is the correct answer as it accurately describes the outcomes of the treaty concerning Germany.
Step-by-step explanation:
The 1919 peace treaty negotiations in Paris, known as the Treaty of Versailles, resulted in several conditions imposed upon Germany by the Allies. Though President Woodrow Wilson proposed idealistic principles in his Fourteen Points, including the end of secret treaties and the promotion of self-determination, the eventual terms of the treaty were significantly more punitive towards Germany. The treaty stipulated extensive German reparations, territorial losses, and a clause mandating Germany to accept responsibility for the war, all designed to weaken the country and compensate the Allies for their losses.
Option D is the correct answer to the student's question. The terms included reparations from Germany, disarming the country, and territorial gains for the Allies. Options A and B, calling for leniency towards Germany and an end to secret treaties respectively, were not realized in the treaty. Option C, suggesting free trade across all of Europe, was not a primary focus of the negotiations. Overall, the treaty's harsh terms against Germany laid the groundwork for future unrest and directly contributed to the rise of Adolf Hitler and the onset of the Second World War.
