Which of the following statements is incorrect? a. T cell recognition of antigen

Question
Which of the following statements is incorrect?
a.
T cell recognition of antigen epitopes is MHC restricted. Antigens are processed by antigen presenting cells, presented in association with MHC antigens and recognized by the TCR/CD3 complex.
b.
Antibodies are serum glycoproteins that are composed of two heavy and two light chain polypeptides. The region of the antibody molecule containing the antigen binding domains is known as the variable region. The Fc region is in the constant region.
c.
Parasite macromolecules that induce an immune response in the host are known as antigens.
d.
B cells recognize antigens using B cell receptor (BCR). The BCR recognizes epitopes that are highly accessible. The epitopes must be complexed with major histocompatibility complex (MHC) antigens for efficient recognition.
e.
Elevated levels of eosinophils are associated with parasitic and allergic reactions.
