Correct option is D)

HIV infects vital cells in the human immune system such as helper T cells (specifically T cells or T-4 lymphocytes), macrophages and dendritic cells. The T helper cells are a type of T-cell that plays an important role in the immune system, particularly in the adaptive immune system. They help the activity of other immune cells by releasing T cell cytokines. Towards the end of an HIV infection, the number of functional CD4+ T cells falls, which leads to the symptomatic stage of infection called as AIDS (Acquired Immune Deficiency Syndrome).
So, the correct answer is 'Helper T-cells'
