An $\alpha$ helix would be destabilized most by:

A) an electric dipole spanning several peptide bonds throughout the $\alpha$ helix.
B) interactions between neighboring Asp and Arg residues.
C) interactions between two adjacent hydrophobic Val residues.
D) the presence of an Arg residue near the carboxyl terminus of the $\alpha$ helix.
E) the presence of two Lys residues near the amino terminus of the $\alpha$ helix.
