The statement that best describes how Cleisthenes reformed Athenian democracy is: Council members were chosen randomly, and men could present laws for debate in assembly.
Cleisthenes is known for establishing a more direct form of democracy in Athens around 508-507 BCE. He introduced the practice of selecting members of the Council of 500 (Boule) by random lot rather than through elections, which aimed to reduce the influence of wealth and power in the selection of political leaders. Additionally, in this democratic framework, male citizens had the right to present and debate laws in the assembly (Ekklesia). Women did not have this right in Athenian democracy.
