Explanation
The correct option is Chemical purity of the water. Chemical purity of the water is correct because it directly supports the approved learning objective to describe how fresh water sources are selected to produce potable water in the UK. This belongs to the subtopic Potable water 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 Potable water.
