Options

A. Activation
B. Agglutination
C. Neutralization
D. Opsonization

Answer

B

Explanation

(b) Three main events occure in the process of formation of antigen-antibody complex. These are- agglutination, opsonization and neutralization.
(i) Agglutination : When an antibody comes in contact with the antigen, foreign bodies like virus, bacteria etc. it become associated with them and are converted into a mass of harmless, insoluble matter.
(ii) Opsonization : Specific immunoglobulin molecules, surround the antigen over its surface. The phagocytes identify such complexs, engulf them and destroy them.
(iii) Neutralization : Antibodies make the toxins produced by viruses and bactetia inffective and destroy them.
