Final answer:
Passive immunity involves the transfer of antibodies from an immune individual to another. It does not require the recipient's own immune system to produce antibodies. This differs from active immunity triggered by vaccination.
Step-by-step explanation:
Passive immunity refers to the transfer of antibodies from an immune individual to another. This type of immunity does not require the recipient's own immune system to produce antibodies. Examples of passive immunity include antibodies passed from a mother to her fetus through the placenta, or antibodies transferred through breast milk.
An immunization or vaccination typically triggers active immunity, where the body's own immune system produces antibodies in response to the vaccine. This type of immunity provides long-term protection and the development of immunological memory.
Therefore, the transfer of immunoglobulins or antibodies from an immune individual to another is involved in passive immunity (option B).
