The correct answer is option 3: water.
An abiotic resource refers to a resource that is non-living, meaning it does not originate from living organisms. Water fits this definition as it is a substance found in nature, such as rivers, lakes, and oceans.
Additionally, water is considered a renewable resource because it has a natural replenishment process through the water cycle. The water that evaporates from oceans and land surfaces eventually condenses into clouds and falls back to the Earth as precipitation, replenishing the water supply. This cycle allows for the continuous availability of water.
Although options 1 (iron ore), 2 (livestock), and 4 (forests) are all important resources, they are not abiotic. Iron ore is a mineral resource, livestock represents a living organism, and forests are composed of living trees.
Therefore, water is the correct answer as an abiotic and renewable resource.
