How do antibodies recognize microbes or toxins?

0 votes
    Heavy and light chains of the antibody "constant" region detect chemical odors from the microbes.
    There is a lock-and-key type fit between the shape of the antibody and the shape of the antigen.
    "Constant regions" on the antibodies interact with microbes that bear morphological features that mirror the constant region of the antibody.
    all of the above
