Proteins in biological systems are polypeptides that are exclusively made from Lamino acids. A peptide, P , with L-amino acids of a particular sequence always adopts a right-handed alpha helical structure. Under identical conditions, if all the amino acids of the peptide P are changed to D -amino acids, then the expected conformation from the options given below would be
