Which type of immunity is demonstrated by the transfer of a mother's immunoglobulin across the placenta to protect the child?

  • A. Natural active immunity
  • B. Natural passive immunity
  • C. Artificial active immunity
  • D. Artificial passive immunity
Correct Answer: B

Rationale: The immunoglobulin passed from the mother to the child through the placenta is an example of natural passive immunity, making choice B the correct answer. This transfer gives the child temporary immunity to various diseases without their immune system having to work. On the other hand, natural active immunity (Choice A) occurs when the body produces its own antibodies in response to an antigen. Artificial active immunity (Choice C) is achieved through vaccinations, where the immune system is stimulated to produce antibodies against a specific disease. Artificial passive immunity (Choice D) is a temporary immunity that involves the transfer of pre-formed antibodies from another source.
