2. **Add Chlorine**: Chlorine is a powerful disinfectant that can be added to water to kill pathogens. It is effective against bacteria, viruses, and parasites. Adding chlorine to water helps ensure that it is safe for consumption and reduces the risk of waterborne diseases.

3. **Add Lime Water**: Lime water, which is a solution of calcium hydroxide, can also be added to drinking water. It not only helps in killing bacteria and viruses but also boosts immunity. This makes lime water a beneficial addition to drinking water for preventing waterborne diseases.

4. **Combine All Methods**: To effectively prevent waterborne diseases, it is advisable to implement all three methods: boiling, adding chlorine, and adding lime water. This comprehensive approach ensures that the water is made potable and safe for drinking.

Thus, the correct answer to the question is **Option D: All of the above**.
