The Nuremberg Laws did Option A.) “Kept Jews from being German citizens and marked them with a Star of David.”
Established in 1935, the Nuremberg Laws were antisemitic but authorized laws that were imposed on Jews.

This left many Jews in chaos because while it kept them from residing in a certain state, it also prevented them from leaving Germany.
