I would check these as the correct responses, with some statistics:
1) Jewish businesses were vandalized.
- Over 7,000 Jewish businesses were damaged or destroyed in the attacks.
3) Many Jews were killed.
- About 100 were killed in the violence on Kristallnacht.
4) Thousands of Jews were sent to concentration camps.
- Over 30,000 were arrested and sent to the the Dachau, Buchenwald and Sachsenhausen concentration camps.
6) Thousands of synagogues were destroyed.
- Technically speaking, the number of synagogues destroyed was over 1,000, not "thousands" ... but I would still check this answer in spite of that technicality.
Context/details:
In November, 1938, there was rampant destruction of Jewish-owned businesses and synagogues and violence against Jewish people. This occurred on the night of November 9 going on into November 10, 1938, and was called "Kristallnacht," or "The Night of Broken Glass." It was public violence by masses of people, not a specific campaign ordered by the Nazi regime. However, Nazi officials did tell police and firefighters to do nothing -- to let the violence and destruction occur. The next day, Joseph Goebbels, the Nazi minister of propaganda, said that this sort of eruption against the Jews was natural and understandable. He said: "It is an intolerable state of affairs that within our borders and for all these years hundreds of thousands of Jews still control whole streets of shops, populate our recreation spots and, as foreign apartment owners, pocket the money of German tenants, while their racial comrades abroad agitate for war against Germany."
In the days after Kristallnacht, the Nazi government said that the Jewish community itself was responsible for all the damage and destruction, and imposed enormous fines against the Jewish community. They also arrested more than 30,000 Jewish men and sent them to concentration camps which were built to incarcerate Jews and any others that the Nazis perceived to be enemies of the German state.
