Answer 2

The answer is A.

"Maternal passive immunity is a type of naturally acquired passive immunity, and refers to antibody-mediated immunity conveyed to a fetus by its mother during pregnancy. Meternal antibodies (MatAb) are passed through the placenta to the fetus by an FcRn receptor on placental cells. This occurs around the third month of gestation.[2] IgG is the only antibody isotype that can pass through the placenta.[2] Immunization is often required shortly following birth to prevent diseases such as tuberculosis, hepatitis B, polio, and pertussis, however, MatAb can inhibit the induction of protective vaccine responses throughout the first year of life. This effect is usually overcome by secondary responses to booster immunization.[3]

Passive immunity is also provided through the transfer of IgA antibodies found in breast milk that are transferred to the gut of the infant, protecting against bacterial infections, until the newborn can synthesize its own antibodies.[4]"

Answer 3

Natural passive immunity.
