Solution

The correct option is A $α -$ Helix
$α$ helix is one of the most common ways in which a polypeptide chain forms all possible hydrogen bonds(intermolecular and intramolecular hydrogen bond) by twisting into a right-handed screw(helix) with the $N - H$ group of each amino acid residue hydrogen bonded to $C = O$ of an adjacent turn of the helix.
