AAncient Egypt — Nile River.
BAncient Sumer — Mississippi River.
CAncient China — Danube River.
DAncient India — Amazon River.
Explanation
Ancient Egypt developed along the Nile River, whose reliable annual flooding deposited fertile silt on farmland and enabled the emergence of one of the world's earliest and most durable civilizations. Ancient Sumer developed along the Tigris and Euphrates rivers (Mesopotamia). Ancient China's early civilization developed along the Yellow River (Huang He) and later the Yangtze. The Amazon and Mississippi are New World rivers unconnected to Old World Bronze Age civilization emergence, and the Danube runs through Central and Eastern Europe.
