Final answer:
The Dutch Jews faced persecution and discrimination at the time the Frank family went into hiding.
Step-by-step explanation:
The situation for the Dutch Jews at the time the Frank family went into hiding was B) They faced persecution and discrimination.
When the Germans occupied the Netherlands during World War II, they began sending Dutch Jews to extermination camps in the East. The Frank family, who had moved to the Netherlands to escape the Nazis, went into hiding in an annex with others. They were able to survive with the help of Dutch friends involved in the underground resistance, but were ultimately discovered and sent to the camps.
Despite the discrimination and persecution faced by Dutch Jews, there were also instances of assistance from non-Jewish neighbors who hid Jews and protected them from harm during the war.
