The correct Answer is:
To solve the question, we need to evaluate each of the statements provided and determine which one is correct. ### Step-by-Step Solution: 1. **Evaluate Statement (A)**: "Use of incinerators is crucial to the disposal of hospital waste." - Incinerators are indeed used for the disposal of hospital waste. They help in rendering the waste non-toxic and reduce its volume, making it safer for ultimate disposal. - **Conclusion**: This statement is **correct**. 2. **Evaluate Statement (B)**: "Recycling is the only solution for the treatment of e-waste." - While recycling is a significant method for managing e-waste, it is not the only solution. Other methods such as proper disposal, recovery of materials, and safe incineration also play roles in e-waste management. - **Conclusion**: This statement is **incorrect**. 3. **Evaluate Statement (C)**: "Fish-eating birds containing 2 ppm DDT become agents of biomagnification." - Biomagnification refers to the increasing concentration of substances, like DDT, in the tissues of organisms at each successive level of the food chain. Fish-eating birds typically contain much higher concentrations of DDT (around 25 ppm), not 2 ppm. - **Conclusion**: This statement is **incorrect**. 4. **Evaluate Statement (D)**: "Polyblend is a fine powder of bitumen." - Polyblend is actually a fine powder made from recycled or modified plastic, not bitumen. - **Conclusion**: This statement is **incorrect**. ### Final Conclusion: Based on the evaluations: - Statement (A) is correct. - Statements (B), (C), and (D) are incorrect. Thus, the correct answer is **(A)**.
