Answer:
A. a system for the plebeians to maintain political dominance.
Step-by-step explanation:
In 451 BCE, a commission of 10 men known as the decemvirs was formed to lay down the law for the first time. The Twelve Tables, which they completed in 449 BCE, codified centuries-old customary regulations and provided the cornerstone of Roman law as we know it today. The legislation of ancient Rome from the time of its inception in 753 BCE to the fall of the Western Empire in the 5th century CE is known as Roman law. It was used until 1453 in the Eastern, or Byzantine, Empire. All free Roman citizens who were neither patrician, senatorial, or equestrian were referred to as plebeian. Plebeians were ordinary Roman citizens who worked hard to maintain their families and pay their taxes - farmers, bakers, builders, and artisans, for example.
