Antibodies are not usually formed until after exposure to an antigen. B. Antibodies are usually formed until after exposure to an antigen. C. Antibodies are not usually formed until after exposure to an antibiotics.

A

Explanation:

Antibodies are not usually formed until after exposure to an antigen. The presences of an antigen will stimulate the production of antibodies. In hemolytic disease and Rhesus sensitization, the first pregnancy where the feotus is Rh positive and mother is Rh negative, the foetus antigen will cause stimulation of antibodies production usually during delivery most often. So in the first pregnancy, it is after exposure to antigen that antibodies are produced. However, in subsequent pregnancies, there are antibodies already once the foetus is Rh positive the antibodies will attack immediately. Resulting into hemolytic disease.
