The three R’s that will help us to conserve natural resources for long term use are
(a) recycle, regenerate, reuse
(b) reduce, regenerate, reuse
(c) reduce, reuse, redistribute
(d) reduce, recycle, reuse
The three R's that help us to conserve natural resources for long term use are reduced, recycle, reuse.
Reduce: This means less use of natural resources, e.g., save water by repairing leaky taps.
Recycle: This means a collection of materials like plastic, paper, glass etc., to make required things instead of synthesizing or extracting fresh plastic, paper, glass etc.
Reuse: Instead of throwing articles, (e.g., used envelopes) use them again. This is better than recycling because the recycling process uses some energy.
Hence option (d) is correct.
