The answer is D, practices, and A, pleasant and attentive.
Answer:
D. Krogstad is going to try to take his job back from Mrs. Linde, and the audience knows it, but Mrs. Linde does not know that this will happen.
Explanation:
In Henrik Ibsen's play "A Doll's House", the story revolves around the character of Nora and her submissive nature to her husband. The society of the time dictates that wives must be dependent on their husbands, who are lord over them. But in the end, Nora broke that cycle and left her family to do as she pleases.
There are numerous scenes of dramatic irony in the play. One such instance is when Krogstad had been fired from his work by Helmer, and the job was given to Christine Linde. In Act II, we see that Krogstad uses his knowledge of Nora's forgery to get money as a means to manipulate Nora into asking her husband to restore him to his job. We, the audience and everyone else seems to know it but the main person involved Mrs. Linde doesn't seem to have any knowledge of it. This is a dramatic irony as the situation seems to be known by everyone except the concerned person.
