The correct answer is C.
When the nazi party arrived to the German goverment, they started to enact discriminative laws against Jews. First of all, they forced Jews to differentiate themselves from other citizens by wearing a star. Afterwards, Jews were forced to live in ghettos (separated areas in cities).
Finally, as part of the policy called 'Final Solution to the Jewish Question', Jews started to be deported to either concentration camps where they were forced to hard labor (where they mostly produced produced war equipment) until death, or to extermination camps were they were automatically killed.
