Question

in which case does the recipient start making antibodies to the specific disease?
a passive immunity
b active immunity
c when given the antibodies
d passive immunity and when given the antibodies

Explanation:

Active immunity occurs when the recipient's immune system is stimulated to produce antibodies against a specific disease. This can happen naturally (after an infection) or artificially (through vaccination). In passive immunity, pre - formed antibodies are given to the recipient (e.g., through maternal antibodies or injection of antibodies), and the recipient's immune system does not produce its own antibodies.

Answer:

B. Active immunity
