What does the term e-waste refer to?

• A. Discarded edible waste.
• B. Discarded electrical energy waste.
• C. Discarded electronic products such as computers and mobile phones.
• D. Waste produced by water treatment.

Answer: (C)

The term e-waste refers to discarded electronic products such as computers and mobile phones. It focuses on devices that have reached the end of their useful life or become obsolete and are thrown away or recycled. E-waste includes items like laptops, televisions, phones, and their accessories, and it raises environmental and health concerns because these devices contain hazardous substances that must be handled properly.

In contrast, the other options describe things that aren’t electronic products: edible waste is food waste, energy waste isn’t a category for discarded electronics, and waste from water treatment relates to sludge and byproducts of treating wastewater.
