Final answer:
Breastfeeding B. provides significant health benefits to infants by offering passive immunity and reducing the risks of infections and conditions like Sudden Infant Death Syndrome (SIDS).
Step-by-step explanation:
Research has shown that breastfeeding has multiple benefits for infants, such as a lower risk of respiratory tract infections and gastrointestinal infections. This is because antibodies produced in the mother's body are passed to the infant via passive immunity through breast milk. Colostrum, the first form of milk produced by the mammary glands following the delivery of the newborn, is notably important to a newborn's health as it helps boost the newborn's immune system by providing high levels of antibodies and growth factors which are crucial in the early stages of the infant's life.
Additionally, exclusive breastfeeding for the first six months is widely recommended to reduce the risk of Sudden Infant Death Syndrome (SIDS). Evidence suggests that breastfeeding and the avoidance of certain risk factors like secondhand smoke exposure, back-sleeping, and the removal of soft bedding can significantly decrease the occurrence of SIDS.
