The statement that correctly compares the number of civilian deaths of the Allied powers with those of the Axis powers is:
The U.S.S.R. had more civilian deaths than Germany.
This is accurate, as the Soviet Union experienced a staggering number of civilian deaths during World War II, estimated at around 20 million, while Germany's civilian casualties were significantly lower.
The other statements are not accurate:
- China had a very high number of civilian deaths, significantly more than the Axis powers in many cases.
- Great Britain had significantly fewer civilian deaths than Germany during the war.
- The U.S. had far fewer civilian deaths compared to the Soviet Union and China.
Thus, the U.S.S.R. and its high civilian death toll is the correct comparison.
