The correct answer is (c). Roads are man-made infrastructure, while the other options are all natural resources.
Natural capital is the stock of natural resources that are available to a country or region. It includes renewable resources such as forests, water, and minerals, as well as non-renewable resources such as fossil fuels. Natural capital is essential for economic growth and development, as it provides the raw materials for industry and agriculture. It also plays a vital role in supporting human health and well-being, as it provides clean air and water, and a stable climate.
Roads are man-made infrastructure that are used for transportation. They are not a natural resource, and they do not contribute to a country’s natural capital.
