What does upcycling mean?

Correct answer: Making a more useful or higher-value item from an old item

Upcycling is the creative reuse of an old, discarded, or unwanted item to make a new product with greater usefulness, improved appearance, or higher perceived value. For example, an old tyre may be converted into a garden planter or a discarded jar into a storage container. Option B is correct because the original material is retained and its practical value is increased. Throwing an item into a river creates pollution, burning it may release harmful substances, and breaking a new item does not create a useful product. Upcycling is different from ordinary disposal because it extends material life and reduces demand for new resources.
