Incorrect choices:

Correct Answer is C

Explanation

Explanation: The correct answer is c. Failure to thrive. SCID is a severe form of immunodeficiency that affects multiple components of the immune system, leading to recurrent and severe infections and failure to thrive in affected infants.

Incorrect choices:

a. Recurrent ear infections are more commonly seen in other types of immunodeficiency disorders, such as selective IgA deficiency.

b. Chronic fatigue and lethargy may be seen in various medical conditions but are not specific to SCID.

d. Persistent joint pain is not a characteristic symptom of SCID. It may be associated with other autoimmune or inflammatory conditions.

A. Severe allergic reactions B. Chronic inflammation C. Frequent and severe infections D. Autoimmune diseases

Correct Answer is C

Explanation

Explanation: The correct answer is c. Frequent and severe infections are common clinical manifestations of immunodeficiency disorders. The weakened immune system is unable to effectively defend against infections, leading to recurrent and severe infections.

Incorrect choices:

a. Severe allergic reactions are more characteristic of allergies or hypersensitivity disorders, not immunodeficiency disorders.

b. Chronic inflammation can be seen in various conditions, but it is not a specific clinical manifestation of immunodeficiency disorders.

d. Autoimmune diseases result from an overactive immune response attacking the body's own tissues, which is the opposite of immunodeficiency disorders where the immune system is weakened and unable to adequately protect against infections.
