Answer:
The correct option is B. Conservation can make coal resources last longer for growing populations.
Step-by-step explanation:
The results from the observational table show that when efforts were made to conserve coal and the public was given guidance for conservation, then the estimation for coal resources to last increased. As coal is a non- renewable energy source, we cannot say that it will last forever in the world. But by conservation tactics, we can, however, use coal in a better way and can it to last longer.
Other statements like statement A cannot be considered true because we cannot convert coal into a renewable source by our conservation tactics. We can only cause it to last longer.
