C. Passage of IgG antibodies from a pregnant mother to her fetus.
Answer:
passage of IgG antibodies from a pregnant mother to her fetus
Explanation:
Antibodies are passed from mother to baby through the placenta during the third trimester. This helps protect the baby when they are born. The type and amount of antibodies also strongly depends on the immunity of the mother.
Bacteria from the mother’s vagina is passed on to the baby during birth. This helps to build the colony of bacteria in the gut that contributes to their immunity.
Thrn after birth, more antibodies are passed on to the baby in colostrum and in breast milk.
