In the diagram below,the plane drawn behind the peptide bond indicates the: A)absence of rotation around the C-N bond because of its partial double-bond character. B)plane of rotation around the C _$\alpha$ -N bond. C)region of steric hindrance determined by the large C=O group. D)region of the peptide bond that contributes to a Ramachandran plot. E)theoretical space between -180 and +180 degrees that can be occupied by the $\phi$ and $\Psi$ angles in the peptide bond.
