The virus effects the red blood cells
The virus effects the white blood cells

The Correct Answer is B
A. The virus affects the red blood cells
HIV primarily affects CD4+ T-helper white blood cells, not red blood cells.
B. The virus affects the white blood cells
HIV destroys CD4+ T-cells, weakening the immune response, leading to immunodeficiency.
C. The virus affects the platelets
Platelets are involved in clotting, not in the immune deficiency caused by HIV.

Although medications for HIV may affect the liver, HIV itself targets the immune system, not liver cells directly.
