The correct answer is D. All of the above.
The Treaty of Versailles was a peace treaty between Germany and the Allied Powers that was signed on 28 June 1919. The treaty was very harsh on Germany, and it is often blamed for the rise of the Nazi Party. The Nazi Party was a political party in Germany that was led by Adolf Hitler. The party came to power in 1933, and it quickly began to rearm Germany. Japan was also a rising power in the early 20th century. The country was ruled by the Emperor, and it had a strong military. Japan began to expand its territory in the 1930s, and it invaded China in 1937. England and France were two of the most powerful countries in the world in the early 20th century. However, they were both weakened by World War I. England and France were also facing economic problems in the 1930s. These problems made it difficult for them to stop Japan and Germany from expanding.
All of these factors contributed to the outbreak of World War II.
