Explanation:
A prominent difference between active and passive immunity is that active immunity is developed due to the production of antibodies in one's own body, while passive immunity is developed by antibodies that are produced outside and then introduced into the body.
The right answer is Exocytosis.
In a eukaryotic cell, exocytosis is a mechanism of material release by invagination of the cytoplasmic membrane. It consists of a spillage of the products of a vesicle outside the cell, by fusion of the plasma membrane with the membrane of this vesicle.
