Explanation:
Detailed explanation-1: -Acquired immunity is immunity that develops with exposure to various antigens. Your immune system builds a defense against that specific antigen. Passive immunity is due to antibodies that are produced in a body other than your own.
Detailed explanation-2: -The agglutination of red cells in this way is correctly called haemagglutination, although it is often simply referred to as agglutination. It takes place when serum/plasma antibody (e.g. anti-A) is mixed with red cells carrying the corresponding antigen (i.e. A antigen).
