The statement that correctly compares the number of civilian deaths of the Allied powers with those of the Axis powers during World War II is:
The U.S.S.R. had more civilian deaths than Germany.
The Soviet Union (U.S.S.R.) suffered incredibly high civilian casualties during the war, significantly exceeding those suffered by Germany. In fact, estimates suggest that the U.S.S.R. lost around 13-15 million civilians, while Germany's civilian casualties were much lower, around 1-3 million.
The other statements in the list do not accurately reflect the historical data regarding civilian deaths during World War II.
