Explanation

Antonino Pio was a Greek emperor who ruled from the year 86 until the year 161, he was a magistrate during the rule of Hadrian and thanks to his reputation was chosen as the heir to the throne of Hadrian. His reign was characterized by the peace that was lived during those years because he invested the money of the empire in improving living conditions and instead of persecuting Christians, he protected them. On the other hand, Marcus Aurelius was a Greek emperor who ruled from the year 121 until the year 180. Unlike his adoptive father (Antonino Pio), as emperor of the Roman Empire, he led military forces to persecute Christians because they were believed to be immoral. So, the correct answer is C. Aurelius killed Christians, while Pius was good to his people and kept the peace.
