The correct answer is - B. It is released from a transporting medium.
After the erosion occurs, the sediments are then transported by certain medium, like the water and the wind. When the transporting medium losses its carrying power, the sediments are released. As they are released, they create new land forms, varying from sand dunes, to beaches, fertile soils, to lagoons... All of the land forms created by the deposits of sediments have the characteristic of being made out of fine particles, mostly of sand.
