Answer

**Step-by-Step Text Solution for the Question on E-Waste:**

1. **Definition of E-Waste:**
- E-waste, or electronic waste, refers to discarded electrical or electronic devices. This includes items such as computers, televisions, radios, and mobile phones.

2. **Understanding the Options:**
- The question presents multiple options regarding the nature of e-waste. We need to evaluate each option to determine which one is correct.

3. **Evaluation of Options:**
- **Option 1:** "E-waste represents municipal solid waste."
- This option is incorrect. E-waste is distinct from municipal solid waste, which typically includes household waste and sewage. E-waste is specifically related to electronic devices.

- **Option 2:** "E-waste is produced in developing countries and exported to developed countries."
- This option is also incorrect. While it is true that some e-waste may be exported, it is not accurate to say that all e-waste is produced in developing countries. Moreover, the transfer of waste between countries is regulated and often restricted.

- **Option 3:** "E-waste is buried in landfills or incinerated."
- This option is correct. E-waste is often disposed of in landfills or incinerated because it is made up of non-biodegradable materials such as plastics, metals (like iron, nickel, silicon, and copper), and glass. These materials do not decompose easily.

4. **Management of E-Waste:**
- E-waste can be managed through recycling, where valuable materials like copper and nickel can be recovered. However, when recycling is not possible, e-waste is often buried in landfills or incinerated at high temperatures (900 to 1200 degrees Celsius).

5. **Conclusion:**
- The correct answer regarding e-waste is that it is buried in landfills or incinerated, as it consists of non-biodegradable materials.
