Answer:
C
Step-by-step explanation:
The correct answer is C) 1.2 million.
With the invasion of Poland in September 1939 and the subsequent annexation of Austria and Czechoslovakia, approximately 1.2 million Jews came under Nazi control. This number includes about 300,000 Jews in Austria and Czechoslovakia, and about 900,000 Jews in Poland. Many of these Jews were later sent to ghettos and concentration camps, where they were subjected to forced labor, starvation, disease, and mass murder as part of the Nazi regime's genocidal policies.
According to historical records, about 300,000 Jews lived in Austria and Czechoslovakia before their annexation by Nazi Germany in March 1938 and March 1939, respectively. Following the invasion of Poland in September 1939, approximately 3 million Jews were living in Poland, of whom about 900,000 were under Nazi control. This brings the total number of Jews under Nazi control after the annexation of Austria and Czechoslovakia to around 1.2 million.
