D. Christianity spread throughout the empire after Constantine's conversion.

Explanation:

Christianity became legal in the Roman Empire after the proclamation of the edict of Milan in 313 made by the emperor Constantine I. Following this event, Christians not only stopped being persecuted but, instead, Christianity spread out throughout the empire. Christianity was finally declared as the official religion of the Roman Empire by the emperor Theodosius I with the edict of Thessalonica in 380. Following Theodosius' death, the empire split in two parts: the Western Roman Empire with capital in Ravena, and the Eastern Roman Empire, also known as the Byzantine Empire, with capital in Constantinople. Therefore, Christianity not only was kept as the official religion of both empires but it also was promoted and spread in all of their territories.
