Bacterial lipopolysaccharide (LPS), a T-independent antigen, stimulates antibody production in mice. Which of the following is incorrect?
A) The antibody produced will be predominantly IgM.
B) Memory B cells will not be induced.
C) IL-4 and IL-5 are required for the production of antibody during the response.
D) The polymeric nature of the antigen crosslinks B-cell surface receptors.
E) B cell activation involves phosphorylation of intracellular molecules.

i feel.....C is wrong...IL 4 and IL 5 are required for class switching of Igs....not for production of primary immunoglobulins....
rest all are fine
whats the answer but...

C
T-independent antigens, because they do not generate T cell-derived cytokines, do not produce IL-4 or IL-5. Thus, no isotype switching or memory cell induction occurs in the response to T-independent antigens.
