Vedclass · Answer

(B) Passive immunity is a type of immunity where preformed antibodies are directly introduced into the body to provide immediate protection. It does not involve the activation of the host's immune system to produce its own antibodies or memory cells. Option $B$ is incorrect because the formation of $B$ and $T$ memory cells is a characteristic feature of active immunity,where the host's immune system is exposed to an antigen and develops a long-term response. Options $A$,$C$,and $D$ are all examples of passive immunity: $A$ (natural passive immunity via placenta),$C$ (natural passive immunity via colostrum),and $D$ (artificial passive immunity via antitoxins).
