The correct answer is B. ...I want to tell you of a marquis...
Step-by-step explanation:
In literature, a framed narrative occurs when the main story or narrative introduces another narrative which creates a story-within-a-story in which the first narrative acts as a frame for the second narrative. This occurs in the excerpt presented because the narrator is first speaking about the actions of kings and sultans but then through the phrase " ...I want to tell you of a marquis..." the narrator introduces a new story that focuses on the actions of a marquis. Therefore, the phrase that indicates the presence of a framed narrative is " ...I want to tell you of a marquis..." because this phrase introduces a story within the main story told.
