Barley, grapes, and olives grew in the coastal regions.
Option C.
Step-by-step explanation:
Ancient Greece had mostly settled down in the coastal regions and the reason responsible for this were the mountains, the ridges which were natural barriers for the country leading them to settle down along the coastal regions in Greece.
So the people during that time, started growing barley, grapes, olives in the coastal regions only and did not raise cattle. Instead of cattle, they raised goat and sheep.
