(b) excess of nitrates in drinking water
Explanation:
Excess nitrate in drinking water, leaves and fruits, changes into nitrite in alimentary canal. It reacts with haemoglobin and produces non-functional met haemoglobin. This reduces O2 carrying capacity of blood. The disorder is called methaemoglobinea. It causes blue baby syndrome and breathlessness in adults.
