The correct option is B Lady Bertram was unable to write about the news.
Option A is the correct answer. Fond of her epistolary methods, Lady Bertram could not spread the news of the Grants going to bath. The announcement of the event was too sudden for her to publish. Her advantage was to write news up and convey the happenings. There is no indication of any of the statements enumerated in options C,D and E, thus making them incorrect.
