The correct answer is C. Mark Twain

Explanation:

Samuel Langhorne Clemens known as Mark Twain was a famous American writer mainly known for his novels The Adventure of Tom Sawyer published in 1876 and the Adventures of Huckleberry Finn published in 1885. Twain was born in 1835 in Florida Missouri but grew up in Hannibal, Missouri which was an inspiration for its novels. Samuel Langhorne Clemens got his pen name "Mark Twain" as he worked on riverboats in which the workers used to shout "Mark Twain" that meant according to the mark, the deep is two (twain is the old word for two) fathoms (12 feet) and thus, it was safe for the boat to cross, even though Clemens had more than one pen name the one he used the most was Mark Twain. Thus, the American author born in Missouri and whose real name was Samuel Langhorne Clemens was Mark Twain.
