The three R`s to save the environment are Reduce, Reuse, and Recycle. Let`s dissect each option to better understand:
1) Rewise: This is not one of the three R`s mentioned in the question. It might be tempting to assume that it fits in with the theme, but it is not a commonly recognized term in the context of environmental conservation.
2) Restore: While this option might seem like a good choice, it is not one of the three R`s being referred to in the question. "Restore" implies returning something to its original state, which doesn`t directly relate to saving the environment.
3) Recycle: This is the correct answer. Recycling involves converting waste materials into reusable materials. It plays a crucial role in reducing the consumption of new resources and minimizing waste disposal.
4) Recall: This option is unrelated to environmental conservation. "Recall" generally refers to the action of remembering or retrieving something.
In conclusion, the correct answer is option 3, Recycle.
