Answer:
Option (e).
Explanation:
The two main types of immune cells are B-cells and T-cells. B cells are antibody producing cells where as T cells are antigen presenting cells.
A scientist claimed that a new blood borne virus can be indestructible by CD8+ cytotoxic T cells and kills many cells. But the medical community quickly denounces the warning as irrelevant because only CD8+ cells are not the only cells that are capable of removing viral infection. Natural killer cells are also involved in virus killing. The blood borne virus can not kill million cells as they are involved in the difficult mode of transmission.
Thus, the correct answer is option (E).

The correct answers are "stimulants; depressants".
