D) allergens.
E) antibody determinants.

Question

Quizplus · Accepted Answer

Antigenic determinants, also known as epitopes, are specific regions on an antigen molecule that stimulate an immune response. These regions are recognized by B cells and T cells and lead to the production of antibodies against the antigen.

Monomers refer to a single unit or molecule, not a specific region on an antigen. Allergens are substances that can cause an allergic reaction, but not all antigens are allergens. Antibody determinants are not a commonly used term in immunology.
