Answer:
A. Elimination of the Jews was not moving quickly enough
Step-by-step explanation:
The PF text book states:
"the "Final Solution" was the plan to effectively and systemically eliminate every Jew in Europe. Millions of Jewish people were already held in camps...however, as the war was turning against them, the Nazis transitioned the concentration camps from labor camps to killing grounds. Under the Final Solution, Nazi officials set up three killing centers in Poland—Belzec, Sobibor, and Treblinka."
