Best answer
Correct answer is (b) Hydrogen

To explain I would say: The secondary structure refers to the shape in which the polypeptide chain exists. There are two possible structures which arise due to the regular folding of the backbone of the polypeptide chain due to hydrogen bonding between CO and NH groups of peptide bond.
