Answer:
Option B
Explanation:
Renewable resources are those that can be grown again and again, like timber. Timber can also be preserved in large quantities (stockpiled) for use by future generations. Though wild-life can be multiplied by suitable conservation measures, they cannot be stockpiled, since wild-life, just as human beings, will also die periodically. So, (B) is the answer. You can easily see that none of the other choices fits in with the meaning of the sentence.
