Final answer:
The Yalta Conference in February 1945 included President Franklin D. Roosevelt, British Prime Minister Winston Churchill, and Soviet Premier Joseph Stalin. They discussed post-WWII arrangements for Europe, the division of Germany, and future plans regarding Eastern Europe and Japan.
Step-by-step explanation:
The Yalta Conference held in February 1945 was a pivotal World War II meeting that included three key leaders: President Franklin Delano Roosevelt of the United States, British Prime Minister Winston Churchill, and Soviet Premier Joseph Stalin. These individuals convened at the Crimean Peninsula, in the Soviet Union, to discuss and establish postwar European order, address wartime strategies, and lay the groundwork for the creation of the United Nations. They deliberated on the division of Germany into occupation zones and the requisite for Germany's unconditional surrender. Additionally, they considered the future of Eastern Europe, with Stalin advocating for a Soviet sphere of influence, ostensibly under the pretense of security concerns.
Although Stalin promised the establishment of coalition governments representing democratic and pro-Soviet constituents in Eastern European countries such as Poland, he later retracted these commitments, which contributed to the origins of the Cold War. Furthermore, the Yalta Conference made significant strides in securing Soviet involvement in the Pacific War against Japan, in return for territorial concessions. As history would recount, the promises made at Yalta about free elections and democratic governments in Eastern European states were not honored by Stalin, leading to prominent ideological rifts that shaped global politics in the following decades.
The correct answer to the student's question, referring to the attendees of the Yalta Conference, is A) Winston Churchill, Franklin D. Roosevelt, and Joseph Stalin.
