Select the correct statement about antigens. A. One antigen may have many different antigenic determinants and may therefore cause the formation of more than one antibody. B. Only small antigens exhibit reactivity. C. "Self-antigens" is another name for incomplete antigens. D. The largest type of antigen is called a hapten

A. One antigen may have many different antigenic determinants and may therefore cause the formation of more than one antibody.

Explanation:

An antigen refers to a substance that triggers the immune system to produce antibody against it. Antigen can come in different forms, namely;

In addition, antigens can also be produce in the body thereby stimulating antibody production likewise.

The correct answer is option A. "One antigen may have many different antigenic determinants and may therefore cause the formation of more than one antibody".

Explanation:

It is true that one antigen can have multiple epitopes, which are the sites of the antigen where an antibody can bind. Therefore, it is possible that a single antigen can cause the formation of more than one antibody. Actually, it is possible that multiple antibodies can be attached to the same antigen at the same time. This forms a stronger bond among antigens and antibodies, and leads to a stronger immunity response from the body.

the answer would be knowledge about cars!
