Vedclass · Answer

(B) Blue baby disease,also known as methaemoglobinaemia,is caused by the high concentration of nitrates in drinking water,often resulting from the heavy use of nitrogen-rich fertilizers in agricultural areas.

Methaemoglobin cannot bind oxygen effectively,leading to tissue hypoxia and a characteristic bluish tint to the skin.
