Which option is not part of the 6 Rs?

Which option is not part of the 6 Rs?

• A. Reduce
• B. Reuse
• C. Rebuild
• D. Recycle

Answer: (C)

The idea here is the waste-management hierarchy used to minimize environmental impact in design and product use. The six Rs outline ways to keep materials out of landfills: Refuse, Reduce, Reuse, Repair, Recycle, and Rot. Rebuild isn’t part of this standard set because it focuses on creating a new item rather than extending the life of what already exists or diverting materials back into use. The other options—Reduce, Reuse, and Recycle—are all core actions within the 6 Rs, while Rebuild doesn’t fit this framework.
