analogy:: natural killer cells are to innate (nonspecific) immunity as
__________ are to adaptive (specific) immunity
○ b cells
○ macrophage
○ helper t cells
○ cytotoxic t cells

Explanation:

First Question (Immunity from Vaccination)

Vaccination introduces a vaccine (artificial exposure) to stimulate the body to produce antibodies, which is active (body's own response) and artificial (not natural infection). So active artificial immunity is correct.

Natural Killer Cells are part of innate immunity (nonspecific). Cytotoxic T cells are part of adaptive immunity (specific, target infected cells), matching the analogy. B cells, Macrophage, Helper T cells have different roles; Cytotoxic T cells directly kill infected cells in adaptive immunity like NK cells do in innate.

Answer:

B. active artificial immunity
