Answer:
d. Ration books.
Explanation:
Anne Frank's "The Diary of A Young Girl" is an autobiography of the young girl and her family's time in the Secret Annex, hiding from being captured by the German Nazis. The book served as an important and touching piece of evidence to what the Jewish people were subjected to during one of the worse genocides in world history.
Once the plan to hide out at the Secret Annex, Miep, a family friend, promised to help them survive. She has already got food, linen, soap, and other necessities ready by the time the Franks and the Van Daana arrived. And she also had to rush off to get ration books, though not in their names as obviously, they'll be identified and captured.
