The correct option is To prevent pollution and protect ecosystems. To prevent pollution and protect ecosystems is correct because it directly supports the approved learning objective to interpret information about waste water treatment processes. This belongs to the subtopic Waste water treatment within Using the Earth's resources and obtaining potable water, so the explanation must stay tied to that curriculum context.

Misunderstanding Waste Water Treatment Steps
Students often confuse the stages of waste water treatment, thinking that all processes happen simultaneously rather than sequentially.
