Answer:
C.) protection of German blood and honor.
Step-by-step explanation:
In 1935, the Nazis passed two laws at their party congress in Nuremberg: the Reich Citizenship Law and the Law to protect German Blood and Honor. They were racial laws and were clearly anti-Semitic.
These laws took German citizenship from Jews and outlawed marriage and sex between Jews and non-Jews. One important element in the Nazi conceptions was that Jewishness was defined by heredity (that is, on a racial basis) and not by practice (religion).
The Reich Citizeship Law established that a citizen of the Reich must of German blood or Germanic origin; it pushed Jewish people to the margins of society. The second law aimed at ensuring the "purity" of the German nation and barred those with German-related blood to marry Jews or have sex with them.
