The correct option is B Reuse
To conserve natural resources and to save environment, three strategies are followed namely, Reduce, Recycle and Reuse. To reduce is to use less. In recycling process, we collect plastic, paper, glass and metal items and recycle these materials to make required things instead of synthesising or extracting fresh plastic, paper, glass or metal. In the ‘reuse’ strategy, we simply use things again and again. The plastic bottles in which we buy various food-items like jam or pickle can be used for storing things in the kitchen.
