The correct answer is: The Allies prosecuted the Nazis as war criminals at the Nuremberg trials.
During and after World War II, as evidence of the Holocaust became known, the Allies took significant steps to hold those responsible accountable. This included the establishment of the Nuremberg Trials, where leading Nazi officials were tried for war crimes, including crimes against humanity related to the Holocaust. The other options listed do not accurately represent the actions taken by the Allies in response to their findings.
