Which countries were considered the Axis powers in World War II until Italy's change of sides?

The Axis powers in World War II originally consisted of Germany, Japan, and Italy. These three countries formed a military alliance against the Allies, which included countries like the United States, the Soviet Union, and the United Kingdom. Their collaboration was driven by mutual interests in territorial expansion and opposition to communism and democracy.

Italy's role as one of the Axis powers changed in 1943 when it switched sides to join the Allies after the fall of Mussolini's regime. This shift marked a significant turning point in the war. While the other countries listed in the answer choices may have had involvement in the war, they did not form part of the Axis alliance in the same capacity as Germany, Japan, and Italy.
