There are five classes of antibodies: IgA, IgD, IgE, IgG and IgM. Following diagram is that of a specific class of antibodies. Observe the diagram and answer the questions listed below the diagram: (i) To which class of antibodies, this antibody belongs to ? (ii) Identify the parts of the diagram labelled as A and B. (iii) Give the name of the part of antibody which binds the antigen. (iv) Which type of immune system is formed by the antibodies?

IgD protects the body fluids and also stimulates phagocytes and complement system. III. IgE acts as mediation in allergic response. IV.
