Final Answer :
D
Explanation :
Sediment is the best choice because it is a significant source of water pollution in terms of total mass. Sediment can be composed of organic and inorganic materials and can carry pollutants such as pesticides, heavy metals, and pathogens, which can have harmful effects on aquatic life and human health. Sediment can also cause physical damage to aquatic ecosystems by smothering habitats and altering water flow.
