Solution
The correct option is A IgA
Colostrum is the first form of milk produced by the mammary glands of mammals (including many humans) immediately following delivery of the newborn. Colostrum contains antibodies to protect the newborn against disease.
IgA is the predominant immunoglobulin in external secretions such as breast milk (colostrum), saliva, tears and mucus of bronchial, digestive, genitourinary tracts.
IgG is the only antibody that can cross the placenta and confer immunity to the foetus.
IgE is a mediator in allergic response.
IgM activates first in initial attack of antigen.
