Correct answer: D. B, C and E onlyकेवल B, C और E
Explanation
Dioxins are mainly unintended by-products of human activities: incineration of chlorinated waste such as plastics (B), chemical processes like chlorine bleaching and herbicide/pesticide manufacture (C), and fuel combustion including diesel engines (E). Forest fires and volcanoes also release small amounts, but the major (anthropogenic) sources give B, C and E only.डाइऑक्सिन मुख्यतः मानवीय गतिविधियों के अनचाहे उपोत्पाद हैं: प्लास्टिक जैसे क्लोरीनयुक्त कचरे का भस्मीकरण (B), क्लोरीन ब्लीचिंग और शाकनाशी/कीटनाशी निर्माण जैसी रासायनिक प्रक्रियाएँ (C), तथा डीज़ल इंजन सहित ईंधन दहन (E)। वनों की आग और ज्वालामुखी भी थोड़ी मात्रा में इन्हें छोड़ते हैं, परंतु प्रमुख (मानवजनित) स्रोतों के आधार पर उत्तर केवल B, C और E है।More People, Development and Environment questions
