Question

Which of the following statements about immunological disorder is correct
A)Bottle-fed infants are less likely to develop food allergies than are breast-fed infants.
B)Primary immunodeficiences include malnutrition and AIDS.
C)Autoimmune disorders are hypersensitivity reactions against self-antigens.
D)Secondary immunodeficiences are genetic or developmental defects.

Accepted Answer

Autoimmune disorders occur when the immune system attacks self-antigens, mistaking them as foreign invaders. Choices A and B are incorrect because bottle-fed infants are actually more likely to develop food allergies, and malnutrition and AIDS are examples of secondary immunodeficiencies. Choice D is incorrect because secondary immunodeficiencies are acquired, not genetic or developmental.
