The correct answer is B) allowed some of them to become citizens.
A reason why most conquered people remained loyal to Roma was that Rome allowed some of them to become citizens.
The expansion of the Roman empire brought questions about the legal status of the people conquered. The Roman Empire allowed those people to maintain their culture and traditions but were treated as citizens. Not as a native-born citizen of Rome, as their people were, but the conquered people were protected from invasions and had the opportunity to make trade deals. But these people had to pay tribute to the Emperor and they had to enroll the Roman Army. So yes, the Roman Empire did not treat bad people from its colonies, indeed, allowed many of them to be citizens of Rome.
