Question

A human body cell is invaded by a new virus that the body has never encountered before. The cell displays the virus's antigens on the cell's membrane. Which of the following best describes what happens next in the body's cell-mediated immune response sequence?

Answer 1

a. B lymphocytes insert into the infected cell and use antibodies to attack and destroy the virus.
b. Helper T cells detect the virus antigens on the infected cell and activate cytotoxic T cells.
c. Memory T cells quickly respond to the virus antigens on the cell by producing cytotoxic T cells.
d. Phagocytes recognize the antigen markings on the infected cell and insert antibodies to destroy the cell.
