The right option is; A. Animal wastes will run into the river with every rainfall.

The expanded grazing area of cattle will negatively influence the river that runs along the land as animal wastes will be transported into the river with every rainfall. The release of animal wastes in the river can affect the water quality of the river because of the pathogens that are present in cattle feaces. Also, it will provide increased potential for toxic algae blooms in the river.
