Solution
The correct option is A True AIDS virus destroys the immune system by attacking white blood cells called CD4 cells. HIV gets inside the CD4 cells and make copies of itself and then kills the CD4 cell. The new HIV copies find other CD4 cells to attack them. Thus, it destroys the immune cells, therefore reduces immunity.
