The correct answer is A. flood plain.

A flood plain is a wide, flat area of land adjacent to a river that is formed by the erosion of the river's banks and the deposition of sediment during floods. The river erodes its banks over time and the sediment it carries is deposited on the flood plain, creating a flat, fertile area. Flood plains can be several miles wide and are typically used for agriculture and development.

Oxbow lakes are formed by meandering rivers, where a loop of the river is cut off and forms a curved lake. Alluvial fans are cone-shaped deposits of sediment that form where a river or stream flows out of a narrow canyon or valley onto a flatter plain. A tributary is a smaller river or stream that flows into a larger river.
Which feature is formed when sediment erodes away from the area as a result of a river’s flow?

beach
waterfall
deltas
