Answer:
C. Supporting Nora’s claim that Torvald does not respect her as an equal.
Step-by-step explanation:
"A Doll's House" by Henrik Ibsen focuses on the character of Nora Helmer whose life as a housewife seems to be restricting her inner desires. The play is a criticism of the patriarchal society's belief of what a wife/woman is supposed to be and Ibsen wants to address the issue through this story.
In the given passage/extract from the play's Act III, we see Nora and Torvald in conversation, a serious conversation as husband and wife. And as Nora pointed out, this was the first time in more than eight years of marriage that they're having a serious conversation between them. Nora points out how she's been nothing but a "doll" to both her father and then her husband. And now, she wanted to do things right by herself, fulfilling her desires and making herself happy despite it meaning she had to leave her husband and children.
And in response to his wife's admission, Torvald's response that "playtime shall be over, and lesson-time shall begin", we can feel that he's not that really changed despite his wife's dilemma.
This husband-wife exchange supports Nora's claim that her husband did not respect or treat her as an equal.
Thus, the correct answer is option C.
