Answer:

d. secondary structure ... hydrogen bonds

Explanation:

The secondary structure of a polypeptide corresponds to localized regions of orderly structure stabilized by hydrogen bonds between the backbone groups -NH and C = O and in which no hydrogen bonds involving the side chains participate. The secondary structure of the polypeptide is characterized by its ability to curl or fold, the folds being maintained by the polypeptide chains.
