The map shows the main streams and the rivers near City A and City B, as well as the nearby factories and farmland. The arrows in the diagram show the direction of the water flow. City A gets its water from the sunset River and City B gets its water from the Moth Lake. A liquid herbicide was applied to a farmland. Based on the information in the map shown, which city would most likely have the best water quality and why? Choose the best answer.
Select one:

City A because there are no pollution sources upstream.

City B because it is fed by two rivers instead of just one.

City B because it is next to a lake which would have more clean water available.
