Solution
The correct option is D delta
Delta.
When large amounts of alluvium are deposited at the mouth of a river, a delta is formed. The river slows down at the mouth, so it doesn't have enough energy to carry all the silt, sand, and clay anymore. These sediments form the flat, usually triangle-shaped land of a delta.
