Part A
The best answer that describes the relationship between Anne and her father in The Diary of Anne Frank, Act I, is:
C. Anne grows increasingly annoyed by the way that Mr. Frank worries about and fusses over her.
This choice captures the tension in their relationship during a time when Anne is navigating her adolescence and feeling restricted by both the situation they are in and her father's protective nature.
Part B
The quotation that best supports the answer to Part A is:
B. It'll be hard, I know. But always remember this, Anneke. There are no walls, there are no bolts, no locks that anyone can put on your mind . . . remember the battle you had with your mother the other day on the subject of overshoes? . . . Well now, you see, for as long as we are here you will never have to wear overshoes!
This quotation illustrates Mr. Frank's protective concern for Anne, which aligns with choice C in that Anne is growing increasingly annoyed by this fussing and overprotection. It shows his desire to comfort her and alleviate her fears but also indicates how their relationship dynamics may be straining her ability to express her feelings freely.
