T-helper cells also known as CD4 cells are white blood cells which protects our body from infection. When any virus or bacteria attacks the body, these cells become active and provides immunity to the body. The HIV cells on entering the body, attack and destroy the helper T- cells. Thus the immunity of the body is reduced in HIV infected persons.
Hence the correct option is D.
