Move the plot:
Flat characters—minor figures that play a supporting role in the story—are used to move the plot along, providing subtle exposition. Such characters do not undergo substantial change or growth in the course of a story. They are also known as "two-dimensional characters" or "static characters."
I believe the best answer for this is that the tailor's wife is irritated at the couple for disproving her theories. She is frustrated that she cannot figure out why they are a couple, and once she reaches an acceptable conclusion, it is disproven when Mrs. Tall becomes pregnant. This can only serve to exacerbate the tailor's wife's irritation and frustration. You can also determine that this is the answer through the process of elimination, as none of the other answers really seem suitable. I hope this helps.
