Official Solution & Explanation:
Correct Answer: Option B(कीटनाशक)
कीटनाशक (Pesticides, जैसे DDT, BHC आदि) सिंथेटिक रासायनिक यौगिक होते हैं जो पर्यावरण में लंबे समय तक बने रहते हैं और इनका जैविक अपघटन नहीं होता। अतः ये गैर-बायोडीग्रेडेबल प्रदूषक हैं।
Chemical pesticides are synthetic persistent compounds that resist microbial degradation and bioaccumulate in food chains, classifying them as non-biodegradable.
