Question

Immunity that develops in foetus after receiving antibodies from mother's blood through placenta is

• A. naturally acquired active immunity
• B. artificially acquired active immunity
• C. naturally acquired passive immunity
• D. artificially acquired passive immunity

Answer 1

The correct option is C naturally acquired passive immunity

The antibodies which foetus receives from mother's blood through placenta are not produced in the body of the foetus so, it is a type of passive immunity and because these antibodies were developed in mother's body due to repeated exposure to antigens, this is a naturally acquired immunity

So, the correct answer is 'naturally acquired passive immunity'
