Answer:
B). Organic Material
Explanation:
Sediments are described as the collection of small particles, particularly dirt, that precipitate from a river or other body of water. It includes fragments of rock, fossils(remains of plants, as well as animals), and the minerals that move through the pace of the water in the river and deposited to a distinct place. The element that sediments do not include is 'organic material' as the only organic material found in sediments are fossils and that too in a very little amount(even less than 1%) because the organic material gets destroyed and through the forces of water during erosion and thus, they don't settle in the bottom. Thus, option B is the correct answer.
