Answer:
The floodplains provided fertile soil for growing crops.
Explanation:
In the fertile crescent, the most important floodplain is that of Mesopotamia, between the rivers Tigris and Euphrates.
This area of the world is not only where agriculture was first attested, but also the region where the first human civilization emerged: Sumer.
And the floodplain was crucial for this. The rivers flooded their banks with nutrients that were carried in sediments. These nutrients made the soil more fertile, allowing for easier and more productive agriculture, which produced the necessary food surpluses that are required for the development of early civilization.

The groundwater replenished by the precipitation, streams, and rivers. Option D is correct.
<h3>What is groundwater replenished?</h3>
The technique by which surface water travels from the covering land surface into the groundwater basement is known as groundwater recharge (or replenishment).
Surface water can be replenished by flowing through the dirt and groundwater, or by injecting water rapidly into the groundwater through wellheads.
This process of recharge is getting done by precipitation, streams, and rivers
Therefore, option D is correct.
