(B) The Bible — Johann Gutenberg printed the Bible around 1448 using his new printing press with movable type, making it the first book printed by him.
The textbook (Chapter 5) identifies Gutenberg's first printed book as the Bible. The Diamond Sutra is the oldest Japanese printed book (AD 868). Students must not confuse the two. In MCQs, recall the exact fact: Gutenberg → Bible; oldest printed book in Japan → Diamond Sutra.
