NEED HELP PLEASE!

Part B
Which quotation from Anne Frank: The Diary of a Young Girl best supports the answer to Part A?
A. . . . to be honest, I’m not exactly delighted at having a stranger use my things, but you have to make sacrifices for a good cause, and I’m glad I can make this small one.
B. During the daytime we can’t make any noise that might be heard downstairs, and when someone else is there, like the cleaning lady, we have to be extra careful.
C. Mr. Dussel has told me much about the outside world we’ve missed for so long.
D. We wouldn’t have to give a moment’s thought to all this suffering if it weren’t for the fact that we’re so worried about those we hold dear, whom we can no longer help.
