The correct answer is B) the Senate awarded him even more power.
The result of Octavian surrendering all of his power to the Senate was that the senate awarded him even more power.
Octavian Augustus had already planned. After so many years of Emperor exerting total power and control over Rome, in 27 BCE, Octavian decided to surrender his power to the Senate, quitting his consulship. He was beginning his seventh term as consul of Rome. Almost the entire Senate were followers and decided supporters of Octavious, so the Senate did not accept his decision and gave him even more power, arguing that Rome needed to maintain unity.
Because he was exiled by his country and anyone was a liberty to take his life if he returned. Anyone who was caught helping him was going to face consequences.
