यादी क्र. I व यादी क्र. II ची योग्य जुळणी करून खाली दिलेल्या अंक प्रणालीतून अचूक उत्तरे शोधून काढा.
यादी क्र. I:
(a) कार्बनडाय ऑक्साईड
(b) मिथेन
(c) नायट्रस ऑक्साईड
(d) सी.एफ.सी.
यादी क्र. II:
(i) नायट्रोजन खतांचा वापर, पशुंचे टाकाऊ पदार्थ
(ii) शितपेटया, वातानुकुलन यंत्रणा
(iii) निर्वनीकरण
(iv) भातशेती, सखोल पशूपालन

The correct answer is Option B ((a)-(iii), (b)-(iv), (c)-(i), (d)-(ii)).

Key Points:
• Greenhouse Gases and Their Major Anthropogenic Sources:
• Carbon Dioxide (CO₂): Primary sources include deforestation (loss of carbon sinks) and fossil fuel combustion in transport and industries. Hence, (a) pairs with (iii).
• Methane (CH₄): Anaerobic decomposition in waterlogged rice paddy fields and enteric fermentation/manure in intensive livestock farming are major contributors. Hence, (b) pairs with (iv).
• Nitrous Oxide (N₂O): Agricultural activities, extensive application of synthetic nitrogen fertilizers, and livestock waste breakdown release N₂O. Hence, (c) pairs with (i).
• Chlorofluorocarbons (CFCs): Synthetic chemicals used extensively as coolants in refrigerators, air conditioning units, and aerosol propellants. Hence, (d) pairs with (ii).
• Global Warming Impact: These gases trap long-wave terrestrial infrared radiation, driving global climate change.
• Key Takeaway: GHG Sources: CO₂ = Deforestation; CH₄ = Paddy/Cattle; N₂O = Fertilizers; CFCs = Refrigerators/AC.
