B. a-2, b-3, c-1, d-4
C. a-4, b-1, c-3, d-2
D. a-4, b-3, c-2, d-1
Answer: Option B
Solution (By Examveda Team)
Drinking water with high nitrate can cause a fatal disorder called Methemo-globinemia.Nitrous oxide is a greenhouse gas and it destroys the Ozone layer.
An overabundance of nutrients like nitrogen and phosphorus in water leads to Eutrophication.
Cadmium is a toxic heavy metal, present as a contaminant in zinc and phosphatic fertilizers are fatal to our Heart and kidney.
