Show answer & explanation
Correct answer: D. (A), (B), (C) onlyकेवल (A), (B), (C)
Explanation
Nutrient leaching (A), metal contamination (B) and salinity/alkalinity (C) are all soil-related degradation problems. Ozone depletion (D) is a stratospheric atmospheric problem and fine aerosols in ambient air (E) are an air-pollution problem — neither belongs to soils. Hence (A), (B), (C) only.पोषक तत्व निक्षालन (A), धातु संदूषण (B) तथा लवणता/क्षारीयता (C) — ये सभी मृदा-अवक्रमण की समस्याएँ हैं। ओजोन क्षरण (D) समतापमंडलीय वायुमंडलीय समस्या है और परिवेशीय वायु में महीन एरोसोल (E) वायु प्रदूषण की समस्या है — दोनों मृदा से संबंधित नहीं हैं। अतः केवल (A), (B), (C)।More People, Development and Environment questions
