Final answer:
The Treaty of Versailles required Germany to accept responsibility for the war through a 'war guilt clause' and to pay large reparations to the Allied Powers, provisions that significantly affected Germany post-World War I.
Step-by-step explanation:
The correct answer to the question is: C. Germany had to take responsibility for Allied war losses by accepting a "war guilt" clause. The Treaty of Versailles was signed at the end of World War I and included several punitive measures levied against Germany. Notably, under the war guilt clause, Germany was compelled to accept full blame for starting the war, which resulted in significant repercussions including harsh territorial losses and financial liabilities. In particular, Germany was required to pay reparations amounting to $33 billion to the Allied Powers, surrender territories such as Alsace-Lorraine to France, drastically reduce their military capabilities, and forgo the development of certain offensive weapons. This treaty sowed the seeds of discontent and economic hardship that would later contribute to the rise of Adolf Hitler and the onset of World War II.
