The Fertile Crescent is the correct answer.

Explanation:

The boomerang-shaped region which extends from the eastern shore of the Mediterranean sea to the Persian Gulf is known as Fertile crescent. The crescent is food growing areas amidst the dry lands. The most fertile land of the crescent is the narrow strip of land between the rivers Euphrates and Tigris. Both of them flow in the same direction and before entering into Persian gulf they combine. This area was called Mesopotamia by the Greeks. Although rainfall is scarce in the region, it is abundant with water and nutrients and water of the river gets into the soil and provides nutrition for the plants to grow.
