The correct option is Soil erosion. Soil erosion is correct because it directly supports the approved learning objective to explain that extracting raw materials by quarrying and mining causes environmental impacts. This belongs to the subtopic Ways of reducing the use of resources within Life cycle assessment and recycling, 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 Ways of reducing the use of resources.
