Correct answer: D. N2O
Explanation
NO, NO2 and the NOx group are the classic nitrogen-oxide air pollutants (from combustion and vehicles) that cause smog and acid rain and are regulated in ambient air standards. Nitrous oxide (N2O) is mainly treated as a greenhouse gas rather than a conventional air pollutant.NO, NO2 और NOx समूह पारंपरिक नाइट्रोजन-ऑक्साइड वायु प्रदूषक हैं (दहन और वाहनों से) जो धूम-कोहरा और अम्लीय वर्षा उत्पन्न करते हैं और परिवेशी वायु मानकों में नियंत्रित हैं। नाइट्रस ऑक्साइड (N2O) को मुख्यतः ग्रीनहाउस गैस माना जाता है, पारंपरिक वायु प्रदूषक नहीं।More People, Development and Environment questions
