The cell in the human body invaded by the human immuno-deficiency virus (HIV) is T-helper cell.
Explanation:
HIV is a retrovirus that primarily targets T-helper cells, specifically the CD4+ T-helper cells. These cells play a crucial role in the immune system by helping in the activation of other immune cells such as B-cells and cytotoxic T-cells. HIV enters the T-helper cells by binding to a specific receptor called CD4, which is present on the surface of these cells.
Once inside the T-helper cells, HIV uses its own genetic material to replicate and produce new virus particles. This leads to the destruction of the T-helper cells, which weakens the immune system and makes the body vulnerable to various infections and diseases.
HIV also targets other immune cells such as macrophages and dendritic cells, but T-helper cells are the primary target. The destruction of these cells ultimately leads to the development of acquired immunodeficiency syndrome (AIDS), which is a life-threatening condition.
In conclusion, T-helper cells are the primary target of HIV in the human body, which leads to the destruction of these cells and weakens the immune system.

HIV destroys CD4/ T-cells by using their replication machinery to create new copies of the virus. This ultimately causes the CD4 cells to swell and burst.
When the virus has destroyed a certain number of CD4 cells and the CD4 count drops below 200, a person will have progressed to AIDS. thus,op A.
