   C. The Agora

Explanation:  The Agora was the central public space in the Greek citiy-states, the main square for several purposes. One of the purposes was the market place, but in addition there were held public meetings, assemblies, art events. In a word, it was the place or centre of political, artistic, and commercial life in the Greek city-state. In literal translation from the Greek language, Agora means a meeting place, gathering place or assembly.
