Which of the following is a genetic disease that results in lack of production of antibodies?
agammaglobulinemia
myasthenia gravis
hiv/aids
chronic granulomatous disease

Option A. "agammaglobulinemia"

Explanation:

Agammaglobulinemia is defined as the group of genetic immune deficiencies due to low concentration of antibodies in the lymph that is caused by the lack of specific lymphocytes in the blood.

Agammaglobulinemia generally caused bacterial infections that results from  failures in immune responses due to defects in B-lymphocytes. B-lymphocytes are responsible for the production of antibodies. Mostly males with X-linked type agammaglobulinemia show signs of bacterial infections, after the IgG antibodies from the mother have been depleted.

Hence, the correct option is A.
