B) The peptide bonds in the α -helix coil back on themselves.
C) Both α -helices and β -sheets can be found as part of tertiary structure.
D) All of these

All statements are true regarding the structure of proteins. The peptide bonds in β-sheets are indeed extended, allowing for the formation of a sheet-like structure. In α-helices, the peptide backbone coils back on itself, forming a helical structure. Both α-helices and β-sheets can contribute to the tertiary structure of a protein, as they are elements of secondary structure that, when folded further, contribute to the overall three-dimensional shape of the protein.
