Question

Quizplus · Accepted Answer

Autoimmune disorders occur when the immune system mistakenly attacks self-antigens, which can lead to damage or dysfunction of a person's tissues or organs.

Note: A is incorrect because breastfed infants actually have a lower risk of developing allergies, including food allergies, than bottle-fed infants. B is incorrect because primary immunodeficiencies are genetic defects that result in a weakened immune system, while malnutrition and AIDS are secondary immunodeficiencies that are caused by external factors. D is incorrect because secondary immunodeficiencies are caused by external factors, such as infections or drugs, rather than genetic or developmental defects.
