Question 3

C. Burkitt's lymphoma

Explanation: Burkitt's lymphoma is the rare form of cancer or proliferation of B cell and plasma cells and it causedby translocationof c-myc oncogene. Common variable immunodeficiency (CVID) is the immuno disorder where antibodies are unable to defends against foreign particle like virus, bacteria etc. due to low levels of all antibodies and cause recurrent infections. Bruton's disease is the X-linked inherited immuno disorder where white blood cell doesn't generate mature B cells and results severe antibody deficiency and recurrent infections.

Question 4

E. All of the above are true

Explanation: Type I hypersensitivity is induced by nonparasititic antigens known as allergens. This hypersensitive reaction are stimulated by the production of IgE. When IgE crosslinked by antigens, the IgE antibodies trigger the mast cell or basophils to release primary mediators like histamine, proteases, heparin etc. This reaction can be leads to life-threatening anaphylatic shock.
