Explanation
The correct option is Increased use of water for domestic activities. Increased use of water for domestic activities is correct because it directly supports the approved learning objective to explain why waste water must be treated before it is released into the environment. 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. The other options are incorrect because they either do not answer this learning objective, use a vague statement, or move away from Waste water treatment.
Common mistake
Misunderstanding Waste Water Treatment
Students often think that waste water can be released into the environment without treatment if it looks clean.
