Vedclass · Answer

(D) $1$. Immunity is classified based on how the body acquires it.$2$. Passive immunity occurs when ready-made antibodies are transferred to an individual.$3$. When this transfer happens through natural processes,such as the transfer of $IgA$ antibodies from mother to infant via colostrum,it is termed 'natural acquired passive immunity'.$4$. Since the infant does not produce these antibodies themselves,it is passive,and because it occurs through a natural biological process (breastfeeding),it is natural.
