The correct answer is C. The graph shows that the spread of printing resulted in many more books being produced.
Until 1450 and even in later years, the books were disseminated in copies handwritten by scribes, many of whom were monks dedicated exclusively to prayer and the replication of copies by order of the clergy themselves or of kings and nobles. Despite what is believed, not all the copyist monks knew how to read and write. They performed the role of copyists, imitators of signs that often did not understand, which was essential to copy banned books that spoke of internal medicine or sex. The illustrations and capital letters were decorative and artistic product of the copyist himself, who decorated each copy that he made according to his taste or vision. Each of his works could last up to ten years.
In this context, Gutenberg bet that he was able to make at the same time several copies of the Bible in less than half the time it took to copy one to the fastest of all the copyist monks. This is how Gutemberg invented the printing press, which allowed a greater diffusion of books (and therefore, ideas and knowledge) from 1445.
With the massification of the printing press, and its increasing technological advances, the number of books produced was growing exponentially, as the graphic shows.
