The correct statement based on the characteristics in the chart is:
The Thirty was an oligarchy, the ecclesia was a democracy, and the Mycenaean Palace was a monarchy.
This matches the definitions and characteristics of each government type presented in the chart. The Thirty are described as tyrannical rulers, indicative of an oligarchy. The ecclesia, which involves assembly decisions made by a wide array of members, exemplifies democratic principles. The Mycenaean Palace, with its palatial society and leader (wanax), aligns with the characteristics of a monarchy.
