The correct answer is B. Communists.
During the Holocaust, in addition to Jews, the Nazis targeted and persecuted various groups considered as enemies of the state. Communists were among those who were sent to concentration camps where they were forced to work under harsh conditions and many died due to the brutality and inhumane treatment inflicted upon them by the Nazis.
While Catholics, Atheists, and Muslims also faced persecution during the Nazi regime, the systematic targeting and extermination of Jews and the persecution of Communists were significant aspects of the Holocaust.
