    Reduction in number of killer $T-$cells.
  • C
    Autoimmunity.
  • D
    Non-production.

Answer

Correct option: A.
Reduction to number of helper $T-$cells.

White blood cells are an important part of the immune system. HIV infects and destroys certain white blood cells called $\mathrm{CD}_{4^{+}}$ cells. If too many $\mathrm{CD}_{4^{+}}$ cells are destroyed, the body can no longer defend itself against infection.
