Explanation:

The Yalta conference was the meeting held before the end of World War II (February 4 to 11, 1945) by Joseph Stalin, Winston Churchill and Franklin D. Roosevelt, as heads of government of the Soviet Union, the United Kingdom and of the United States, respectively. It is usually considered the beginning of the Cold War.

It was the continuation of the series of meetings that began with the Moscow conference of August 1942, which took place in the Kremlin and which continued with the Casablanca conference of January 1943, which took place in the former Imperial Palace of Livadia, in Yalta (Crimea), and with the Tehran Conference, November 1943, which took place at the USSR embassy in Iran.

The Yalta agreements were controversial even before the final match in Potsdam. After the death of Roosevelt, Churchill and Stalin were accused of not having accepted an international control over the countries liberated by the USSR. Moreover, no other government was consulted or the decisions taken there were notified.

Regarding the question: The USSR undertook to intervene in the war with Japan three months after the German surrender. In return, it would be given the island of Sakhalin and the Kuril Islands, as well as several privileges.

letter d is correct.
