The answer is option A.
What reasons sedimentation to arise?
Soil debris settles at the lowest of a frame of water. Sediment can come from soil erosion or from the decomposition of flowers and animals. Wind, water, and ice assist to deliver these particles to rivers, lakes, and streams.
Water can wash sediment, which includes gravel or pebbles, down from a creek, into a river, and sooner or later to that river's delta. Deltas, river banks, and the lowest of waterfalls are common areas wherein sediment accumulates.
