Which point of view is used in this excerpt from “advice to youth” by mark twain? go to bed early, get up early—this is wise. some authorities say get up with the sun; some say get up with one thing, others with another. but a lark is really the best thing to get up with. it gives you a splendid reputation with everybody to know that you get up with the lark; and if you get the right kind of lark, and work at him right, you can easily train him to get up at half past nine, every time—it’s no trick at all.

I think the answer is B because if you look up second person POV it says 'you' and the sentence in the story has 'you' in it

the purpose of the heading in the passage is to identify who is telling the story.

this excerpt is part of the book sugar changed the world (2010) written by marc aronson and marina budhos. as the book has been written by two people, the heading "marc" indicates that this specific excerpt is being narrated by aronson. in the fragment, marc describes his grandfather's story after hearing it from his cousin. however, there are other excerpts where budhos is the one that tells the story of her family.

aronson and budhos, who are husband and wife in real life, decided to write sugar changed the world when they found out how sugar, which had an important role in slavery and economy, changed their ancestors' lives.
