Which of the following statements about the symmetry model of allosterism is not true?
A)the protein is an oligomer of symmetrically (or pseudosymmetrically)related subunits.
B)the oligomer can exist in two conformational states,which are in equilibrium.
C)the ligand can bind to a subunit in either conformation.
D)the molecular symmetry of the protein is conserved during the conformational change.
E)none of the above.

All the statements (A, B, C, D) correctly describe aspects of the symmetry model of allosterism, which posits that allosteric proteins are oligomers with symmetric subunits that can exist in multiple conformations, with ligands able to bind to subunits in any conformation, and that the symmetry of the protein is maintained during conformational changes.
