Correct Answer is C
Explanation
Explanation: The correct answer is c. Frequent and severe infections. One of the hallmark features of immunodeficiency disorders is an increased susceptibility to infections. Individuals with immunodeficiencies may experience frequent and severe infections, including bacterial, viral, and fungal infections.
Incorrect choices:
a. Excessive inflammation at the site of infection is not a common clinical manifestation of immunodeficiency disorders. Immunodeficiencies are characterized by a weakened immune response, which may result in a reduced inflammatory response to infections.
b. Hyperactive immune response to allergens is seen in allergies and autoimmune disorders, not immunodeficiency disorders.
