a. Severe combined immunodeficiency (SCID)
Common variable immunodeficiency (CVID)
DiGeorge syndrome

The Correct Answer is B
Explanation: The correct answer is b. Common variable immunodeficiency (CVID). CVID is a primary immunodeficiency disorder characterized by a reduced level of immunoglobulins, particularly IgA, leading to an increased susceptibility to infections.
Incorrect choices:
a. Severe combined immunodeficiency (SCID) is a more severe immunodeficiency disorder that affects multiple components of the immune system, not specifically IgA levels.
c. DiGeorge syndrome is caused by a genetic abnormality and is characterized by a defect in the development of certain organs, including the thymus and parathyroid glands. It may result in immune system abnormalities but does not primarily involve IgA deficiency.
d. Wiskott-Aldrich syndrome is a rare X-linked genetic disorder that affects platelet function and immune system regulation but is not specifically associated with IgA deficiency.

Correct Answer is A
Explanation
Explanation: The correct answer is a. "Practice proper hand hygiene and infection prevention measures."

It is one of the most effective ways to prevent the transmission of pathogens.

Incorrect choices:
a. Hyperactivity and restlessness are not typical clinical manifestations of immunodeficiency disorders. These symptoms are more commonly associated with conditions affecting the central nervous system.
