Question

Zybrea Knight · Accepted Answer

Final Answer : B, Explanation :  Babies are born with a certain level of immunity that they acquire from their mothers, which is called passive immunity. This immunity is obtained from the transfer of antibodies from the mother via the placenta during pregnancy and from breast milk after birth. This passive immunity provides protection to infants until their own immune systems develop fully, which takes about six months.
