B Correct answer
Explanation

John J. Loud patented an early ballpoint pen design in 1888, though it was not commercially successful. The modern ballpoint pen most people use today was developed later by Laszlo Biro in the 1930s. Loud's design was a working ballpoint mechanism, but it was not practical for mass production. Dr. Turing worked in computing, Otto is not a full name, and Roger Bacon lived centuries earlier.
