Answer:
Aristocracy: these were the people at the top of Ancient Greek society. Depending on the region, they enjoyed political rights like the right to vote or to hold public office. They often served in the military, which they considered an honor, and owned businesses.
The Metis: this was the Middle Class. Lacking political rights in most cases, they could still own property, and were regarded as valuable members of society.
Slaves: Ancient Greece was a slaved-based society, and slaves were common, in some areas, the majority of the people. Slaves were property and had no rights whatsoever. However, they could obtain their freedom through merit or by purchasing it.
