All citizens in ancient Athens took part in government by voting in the Senate General Assembly.

In ancient Greek, the democratic system was based in a popular assembly, which was open to all male citizens as soon as they were considered part of the citizenship. This assembly or 'council' was named 'ecclesia' or 'ἐκκλησία' in greek.

This assembly was in charge of the military agenda, nominating and then electing their magistrates and several other subjects related to the city and citizens. Consider that a regular session would have around 6,000 people.

After explaining this brief idea, the most suitable answer would be 'General Assembly'
