Answer: Option C; manage natural resources responsibly
Step-by-step explanation: Natural resources are of two types broadly- renewable and non-renewable. Currently, we have technology which uses non-renewable resources [coal, petrol] more as compared to renewable resources [wind, sun]. That's why pressure on fulfilling the needs is very high on non-renewable resources. If these resources are not used responsibly, it will lead to their exhaustion. Nothing would be left for future generations. More focus should be laid on using these resources efficiently and developing technology which can use renewable resources at affordable price.
