Answer 1

Answer: (B)

Naturally acquired passive immunity

Passive immunity is the type of immunization when a ready-made antibody is directly given to the patient to protect the body against foreign attack. It can be injected artificially or provided naturally by mother milk (colostrum) or by transferring it to the foetus by the placenta.

So the correct option is "Naturally acquired passive immunity".
