The correct answer is option C: the rise of fascist governments in Europe. The rise of fascist governments, led by Adolf Hitler in Germany and Benito Mussolini in Italy, played a significant role in causing World War II. These fascist regimes pursued aggressive territorial expansion and had imperialist ambitions, which led to the invasion of countries such as Poland, France, and the Soviet Union.

To determine the correct answer, you can analyze the historical events and factors that contributed to the outbreak of World War II. It is important to study reliable historical sources, such as textbooks, scholarly articles, and reputable websites that provide accurate information on this topic.

Option A, the rise of democracy in Europe, is not directly linked to the causes of World War II. While the transitions to democracy did occur in some European countries during this period, it was not a direct cause of the war.

Option B, the United States becoming an ally with Great Britain, was a significant development during World War II, but it was not a cause of the war itself. The United States joined the war after the attack on Pearl Harbor in 1941, and its alliance with Great Britain was a response to the ongoing conflict rather than a root cause.

Option D, the Holocaust, was a horrific event that occurred during World War II, but it was not a direct cause of the war. The Holocaust was a systematic genocide perpetrated by Nazi Germany, primarily targeting Jewish people, but it was not the cause of the war itself.

Understanding historical events, their chronology, and their causative factors will help you accurately identify the causes of World War II.
