The right answer is option C. The first codes of law are written down. A good example is the The Napoleonic Code, which is recognized as the first legal code of the modern world, when Napoleon ruled over France in 1804. The Napoleonic Code tried to leave the old feudal system, behind and to modernize the country in order to create a new era different than the previous one. The first codes of law were used as reference for the new republics that left monarchy behind and wanted to achieve a Democratic government.
