Answer: A) Christianity soon became the official religion of the Roman Empire
Explanation: Christians were persecuted in the Roman Empire before Constantine's conversion to Christianity. Since in the Roman Empire religion was polytheistic, that is, pagan, the pagans were not persecuted, nor did the Jews, even though they were under the authority of Rome . After Constantine, by passing the Milan Edict 313 AD, made Christianity one of the religions of the Empire, the persecution of the Christian stopped. Thus, Christianity is aligned with other religions and has not yet become the official religion of the Roman Empire. This was done by Emperor Theodosius 380 AD who proclaimed Christianity as the official religion of the Empire by the Edict of Thessalonica.
