Which of the following is an example of a finite resource?

The correct option is Natural gas.

The correct option is Natural gas. Natural gas is correct because it directly supports the approved learning objective to explain how finite resources from the Earth, oceans and atmosphere can be processed to provide energy and materials. This belongs to the subtopic Using the Earth's resources and sustainable development 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 Using the Earth's resources and sustainable development.
