c. the high salinity of the surface runoff is harmful to freshwater ecosystems.

the runoff of saline soil in the nearby fresh water sources will increase the salinity of water. It will badly affect aquatic plants and animals. the higher concentration of salt will adversely affect the metabolic activities. It may even lead to exosmosis and eventual death of organisms.
