Answer 1

The correct option is D Reduce, reuse, research, recharge

Conservation is defined as the management of the biosphere for the benefit of all life, including humankind. The 4R strategy focuses on conservation, which includes efforts to reduce, reuse, regenerate or recharge, and research.

Reduce stands for minimising the use and wastage of resources. Reuse means the sustainable usage of resources multiple times in different ways. Resources could also be recharged or regenerated if we make a conscious effort to allow the resource to grow back. Finally, research refers to exploring sustainable alternatives and practices to conserve resources. It is imperative for our sustenance.
