The correct answer is B) To be tried by a jury.
What led to the development of democratic principles and was a right of all Roman citizens was the right to be tried by a jury.
We are talking the Roman Law, which has influenced many modern countries. The Roman Empire used the Roman Law to resolve civil trials in a forum. The praetor listened to both parts in a trial. In the case of criminal law, the praetor judges and determine the witnesses for a trial. In ancient Rome, all Roman citizens had the right to be tried by a jury. And this principle is the basis of modern-day democracy.
