• B. Bacteria-related diseases
• C. Congenital disorders
• D. Pollutant-induced disorders

Answer 1

Answer: (C)

Congenital disorders

Answer 2

A congenital disorder is a medical condition that is present at birth. Congenital disorders can be a result of genetic abnormalities, the intrauterine environment, or unknown factors. Sickle cell disease [a group of genetic disorders caused by sickle haemoglobin (Hbs). Hbs molecules tend to clump together, making red blood cells sticky, stiff, and more fragile, and causing them to form into a curved, sickle shape.] and Huntington's chorea (an inherited disorder characterized by degenerative changes in the basal ganglia structures, which ultimately result in a severely shrunken brain and enlarged ventricles, abnormal body movements called chorea, and loss of memory) are congenital disorders.
