The correct answer is D) it helped preserve Roman laws for future European leaders.
Justinian's collection of Roman laws was significant in that it helped preserve Roman laws for future European leaders.
As the Emperor of the Byzantine Empire, by the year 527, Justinian realized that the law in the Empire needed renovation. He wanted to improve the set of regulations that existed in the Eastern Roman Empire and named Trobonian, a Roman official, to supervise the modernization of the Roman law. That is how the Justinian Code was created. It practically focused on religion regulations. However, this Justinian Code influenced other codes and sets of laws all over Europe.
