Answer: C. Civilizations developed in areas well suited for agriculture but relied on trade for everything else.
Step-by-step explanation:
Humanity´s first civilizations were established on the banks of rivers around the time of the Neolithic Revolution (12000 BCE).
The Ancient Egyptians were located on the Nile, the Mesopotamians in the Fertile Crescent on the Tigris/Euphrates rivers, the Ancient Chinese on the Yellow River, and the Ancient India on the Indus.
Rivers provided a steady water source for agriculture, and are a perfect waterway for trade.
