The correct answer is C. He invented a printing press with moveables type and used it to make copies of the Bible.
Explanation
During the Late Middle Ages, the printing of pamphlets or texts such as the bible was carried out by means of woodcut, a technique in which it was necessary to sculpt a wooden board with the text and illustrations of the text, later ink was applied and the paper was put on that table. This technique took a lot of time and effort if it was used in the reproduction of books like the bible because printing only one page could take multiple days, on the other hand, the use of these tables did not allow the copies to be exactly the same after several uses.
For this reason, Gutenberg decided to create his own method, for this he made individual mobile types of iron using wooden molds that he later filled with iron. He also made several models of each one of the letters of the alphabet so all texts could be written harmoniously. The method developed by Gutenberg with individual mobile types made the letters had to be organized (a faster process than sculpting a complete wooden board), besides being metal, besides all copies were exactly the same, this method was called the Gutenberg Printing Press and was mainly use to create multiple copies of the Bible and other documents to allow all the population to have access to them. So, the correct answer is C. He invented a printing press with moveables type and used it to make copies of the Bible.
