The correct answer is B. The best summary of the text is that the Bingleys invite Elizabeth to stay with them and care for her sister Jane. However, when she arrives, they are rude to her.
In the excerpt, Elizabeth Bennet arrives at the country home of the Bingleys to tend to her sister Jane, who has fallen ill. After dinner, Miss Bingley and Mrs. Hurst criticize Elizabeth's manners, describing them as a mixture of pride and impertinence. They also criticize her lack of conversation, style, taste, and beauty.
They mock Elizabeth's appearance, commenting on her wild look, untidy and blowsy hair, and a petticoat that is six inches deep in mud. Despite their criticism, Bingley defends Elizabeth, stating that he thought she looked remarkably well and her dirty petticoat escaped his notice.
Miss Bingley then directs the conversation towards Mr. Darcy, suggesting that he would not wish to see his sister make such an exhibition as Elizabeth did. Mr. Darcy agrees, expressing disapproval of Elizabeth's behavior, considering it conceited and indicative of a lack of decorum.
Bingley, however, defends Elizabeth, stating that her behavior shows an affection for her sister, which he finds pleasing. The conversation shifts to discussing the Bennet family, with Bingley expressing his regard for Jane Bennet while acknowledging their low connections and the unlikelihood of her settling well due to her father, mother, and relations.
Darcy adds that the Bennet sisters' relations and low connections materially lessen their chance of marrying men of any consideration in the world, to which Bingley's sisters heartily agree, indulging in mirth at the expense of the Bennet sisters' vulgar relations.
As Elizabeth enters the drawing-room, she finds the party playing cards and declines the invitation to join, preferring to amuse herself with a book. Mr. Hurst finds her preference for reading over cards rather singular, but Miss Bingley defends Elizabeth, stating that she despises cards and finds pleasure only in reading.
Elizabeth clarifies that she is not a great reader and finds pleasure in many things, including nursing her sister. Bingley acknowledges Elizabeth's role in caring for her sister and expresses hope for Jane's recovery, which Elizabeth appreciates. She then walks towards a table with a few books, and Bingley offers to fetch her more from his library.
Elizabeth assures him that the books in the room are sufficient, and the excerpt concludes.
Therefore, the correct summary is that Elizabeth visits the Bingleys' house to care for her sick sister, but upon her arrival, they are rude to her.
