Final answer:
The inference most supported by the excerpt about the narrator's view of Mrs. Bennett is that the narrator considers her opinions irrelevant.
Step-by-step explanation:
The inference about the narrator that is most strongly supported by the excerpt from the novel concerning Mrs. Bennett is option (b): The narrator finds Mrs. Bennett's opinions irrelevant.
Austen's method of characterizing Mrs. Bennett through actions and dialogue, instead of granting direct access to her consciousness, allows readers to form their own views on Mrs. Bennett's attitudes and values.
Observing Mrs. Bennett from a distance encourages the reader to scrutinize her position and the societal conditions she represents more rigorously.
