Answer:
Option: D) A written legal code that applied to all citizens.
Step-by-step explanation:
The Athenian ruler Draco wrote a legal code that replaced the system of oral law and blood feud. Draco became the first democratic legislator and took it in his hands to change the laws in the Athenian legal system. The main purpose of this law was to reduce arbitrary judgments of punishment and to reduce blood feuds( vendetta) between parties in Athens.
