Answer:
B. Mr. Bennet enjoys watching his family as they figure out their mystery guest.
Step-by-step explanation:
Jane Austen's classic romance novel "Pride and Prejudice" revolves around an Elizabethan English society where wealth determines how eligible a woman is in getting a husband. Moreover, the issue of love is never considered to be a condition for a union, but rather class and family wealth determines how a person is perceived in society.
In the given excerpt from the novel, we see Mr. bennet declaring to his family the secret guest who's coming over for dinner. And the sentence "this aroused a general astonishment, and he beamed with pleasure at being eagerly questioned by his wife and five daughters at once" shows how he enjoys watching them try to figure out who their mystery guest might be.
Thus, the correct answer is option B.
