Answer:
A- Jews were considered outsiders in nation-states built around ethnic identities.
Step-by-step explanation:
Jews fought for their countries (Germany, Poland, Greece...etc..), during WWl and we're loyal to their countries as well. Even though they sacrificed anything for their countries they were still imprisoned due to being 'outsiders' during WW|| and thrown in camps which in many Jews were executed.
