Answer: b - St. Peter and St. Paul
Step-by-step explanation:
St. Peter and St. Paul were the first martyrs, who died at the hands of the Roman emperor Nero. They promoted Christianity in Rome and were killed because of it. In the following centuries, persecution of Christians continued and the most fierce fairies during the Diocletian.
The constant abuse of Christians characterized the earliest period of Christianity in Rome. Only under Emperor Constantine, did the persecution of Christians stop. With the Edict of Milan (Italy) in 313, the emperor allowed freedom of religion, so that Christianity would expand significantly in the coming period. In 387, Christianity became the state religion in ancient Rome.
