Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
Excessive use of fertilizers leads to accumulations of nitrates in the water. In infants, excess nitrate reacts with haemoglobin to form non-functional methaemoglobin that impairs oxygen transport. Methemoglobin is a form of hemoglobin that contains ferric [Fe³⁺] iron and has a decreased ability to bind oxygen. This condition is termed as methemoglobinemia or blue baby syndrome. This disease can damage respiratory and vascular systems and even cause suffocation.
Therefore, the correct answer is option A.
