What statement best describes a significant cause of World War 2?

A significant cause of World War II was the rise of totalitarian regimes in Germany, Italy, and Japan, driven by economic instability and nationalistic fervor after World War I. The Treaty of Versailles imposed harsh penalties on Germany, leading to widespread resentment and the emergence of Adolf Hitler, who sought to expand German territory. Additionally, aggressive expansionist policies by these nations, coupled with the failures of the League of Nations to enforce peace, ultimately culminated in the outbreak of the war in 1939.
