Quizplus · Accepted Answer

The antibodies found in a newborn are mostly acquired through passive immunity, which is the transfer of maternal antibodies across the placenta or through breast milk. The newborn's immune system is not fully developed at birth and needs these antibodies to provide initial protection against pathogens until their own immune system can start producing antibodies. IgM is a type of antibody produced by the immune system, but it is not the primary antibody found in newborns. Therefore, choices A and C are incorrect. Self-made antibodies are produced by an individual's own immune system, which is not fully developed in newborns, so choice B is also incorrect.
