C. Yes, as long as use doesn't exceed availability
Explanation:
Non-renewable resources are resources that can become depleted because they cannot be easily replenished. The most common example of a non-renewable resource is fossil fuels.
In order to use non-renewable sustainably, we must understand the concept of conservation of resources. The sole aim of conservation is to use resources reasonably well so that their availability would not be limited compared to the use they are put to.
Through resource conservation, non-renewable resources can be used sustainably.
