The excerpt from Mark Twain's "Life on the Mississippi" that best shows that the story is told in first person is "I first wanted to be a cabin boy, so that I could come out with a white apron on and a shake a tablecloth over the side, where all my comrades could see me."
Mark Twain wrote his memoirs when he lived in the Mississippi working as a steamboat pilot, before enrolling in the Confederate Army, and his travelings across the river from New Orleans to St. Louis, Missouri. The book was called "Life on the Mississippi," and was written in 1883. The book is about his memoirs, that is why it's written in first person.
The other options of the question were A) Ten minutes later the steamer is underway again, with no flag in the jack-staff and no black smoke issuing from the chimneys. C) then such as scramble as there is to get aboard and to get ashore and to take in freight and to discharge freight. D) Assemble there, the people fasten their eyes upon the coming boat as upon a wonder they are seeing for the first time.
