Final answer:
Nora's awaited miracle was the expectation for a profound change in her husband's character and a selfless act of love to save their marriage, representing an unexpected opportunity.
Step-by-step explanation:
The miracle Nora was waiting for at the end of the play ‘A Doll’s House’ by Henrik Ibsen was not a financial windfall, recovery from illness, or reunion with a loved one. Instead, the miracle she anticipated was D) an unexpected opportunity for her husband Torvald to display a profound change in character and moral perspective, demonstrating a selfless act of love that would redefine their marriage and Nora’s own self-understanding. Despite the complexity of the situation, Nora's hope was that Torvald would take responsibility and sacrifice for her, as she had done for him, to save their relationship — showing that they are equal partners. This expectation was shattered in the climax, prompting Nora to make a drastic decision about her future.
