Question

read the excerpt from act 3 of a dolls house.
krogstad with a searching look at her. is that what it all means? — that you want to save your friend at any cost? tell me frankly. is that it?
mrs. linde: nils, a woman who has once sold herself for anothers sake, doesnt do it a second time.
krogstad: i will ask for my letter back.
mrs. linde: no, no.
krogstad: yes, of course i will. i will wait here until helmer comes; i will tell him he must give me my letter back — that it only concerns my dismissal — that he is not to read it —
mrs. linde: no, nils, you must not recall your letter.
krogstad: but, tell me, wasnt it for that very purpose that you asked me to meet you here?
which evidence from the text best supports the theme that it is better if the truth comes out?
\you want to save your friend at any cost?\
\a woman who has once sold herself for anothers sake, doesnt do it a second time.\
\this unhappy secret must be disclosed; they must have a complete understanding.\
\very well, if you will take the responsibility.\

Explanation:

The theme is about the truth coming out. The option "This unhappy secret must be disclosed; they must have a complete understanding." directly supports the idea that the truth (the unhappy secret) should be made known (disclosed) for a complete understanding, which aligns with the theme. The other options either focus on saving a friend (not directly on truth disclosure), a woman's past actions (not about truth coming out in this context), or taking responsibility (not as directly related to the theme of truth disclosure as the chosen option).

Answer:

"This unhappy secret must be disclosed; they must have a complete understanding."
