Vedclass · Answer

(B) Passive immunity is a type of immunity where pre-formed antibodies are directly introduced into the body to provide immediate protection.When a person is exposed to antigens like those causing tetanus or snake venom,direct injection of antibodies (antitoxins) is required to neutralize the pathogens or toxins immediately.Unlike active immunity,which involves the body's own immune system producing antibodies in response to antigens (like vaccines),passive immunity does not involve the host's immune system in the production of antibodies.Therefore,injecting antibodies is the correct method to obtain passive immunity.
