Ai-b, ii-d, iii-a, iv-c
Bi-c, ii-a, iii-d, iv-b
Ci-d, ii-b, iii-c, iv-a ✓ Correct
Di-d, ii-c, iii-b, iv-a
Correct answer: (C) i-d, ii-b, iii-c, iv-a
Explanation
The correct pairing ties ammonia to water-body acidification, sulphur dioxide to severe respiratory damage, arsenic to blood-kidney harm, and lead to nervous-system and RBC effects.
Ammonia at high levels drives acidification of water bodies.
Sulphur dioxide causes severe respiratory problems and cuts gas exchange across the lung surface.
Arsenic damages red blood cells and kidneys and brings on jaundice.
Lead disrupts the central nervous system and interferes with red blood cell development.
Children are especially vulnerable to lead's neurological effects.
