Option D, IgM
Immunoglobulin M (IgM) is the major subtype of the antibodies detected by agglutination test. This is so because IgM antibodies emerge in the body as soon as the vaccination is received for a longer period of time i.e 1 month.
IgG antibodies cannot be detected because they appear later than IgM.
The agglutination intensity is several 100 times of the agglutination intensity of IgG agglutination antibodies
