Solution
The correct option is B Loss of immunity - HIV; AIDS; virus
The HIV virus is transmitted through body fluid by unprotected sexual activity, blood transfusions, hypodermic needles and from mother to child. Upon acquisition of the virus, the virus replicates inside and kills T helper cells, which are required for almost all adaptive immune responses. When the CD4 lymphocyte count falls below 200 cells/ml of blood, the HIV-host has progressed to AIDS, a condition characterized by the deficiency in cell-mediated immunity and the resulting increased susceptibility to opportunistic infections and certain forms of cancer.Therefore, the correct answer is option B.
