Why did Nazi Germany implement the Final Solution?

I think it's B.

Explanation:

A. Elimination of the Jews was not moving quickly enough

Explanation: The PF textbook states: "the 'Final Solution' was the plan to effectively and systematically 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."

Hope this helps!!!
