o d. siltation

B. Sustainable yield

Explanation:

The renewable resources are resources that are able to renew on their own. Still, that doesn't mean that these resources can provide endless amounts, but it has to be taken in consideration what is the sustainable yield. We can take the trees as a perfect example. The wood is a renewable resource, but in order for it to be renewable, the trees that have been taken down have to be replaced with young saplings, so that they replace in time the ones that have been removed. If that is not practiced, and much more trees are taken down than what are planted, then the trees will eventually come to an end, and after some time there will be no trees left to be used as a resource.
