Which of the following is a renewable resource?

The correct answer is pine trees, as they can be considered a renewable resource. Renewable resources are those that can be replenished naturally over time. Pine trees, when managed sustainably, can be replanted after being harvested. This allows for a continuous supply of timber and other wood products without depleting the resource.

In contrast, coal and petrol are fossil fuels formed from ancient organic materials over millions of years, which means they cannot be replenished on a human time scale. Peanut oil, while derived from a plant, is not typically classified as a renewable resource in the same context as sustainably managed trees because the production of oil requires continuous planting and harvesting, which can be affected by agricultural practices and resource management. Therefore, the best example of a renewable resource in the given options is pine trees.
