- C. When HIV damages a large number of helper T-lymphocytes

Explanation
AIDS is a disorder of the cell-mediated immune system of the body. The virus responsible for AIDS is HIV(Human immunodeficiency virus). There is a reduction in the number of helper T cells which stimulate antibody production by B-cells. This results in the loss of natural defense against viral infection. HIV attacks the immune system, specifically targeting the CD4 cells (T cells). HIV infection progresses through several stages by infecting Helper T cells.
