N is multiplied by 10 for 10 Glycines, then subtract 9 × H

O for removing 9 waters to form each peptide bond as each bond formation removes one water. So, 18 hydrogens and 9 oxygen are removed for peptide bond formation. The general formula of 10 glycine molecule is { $$C }_{ 20 }{ H }_{ 32 }{ O }_{ 11 }N_{ 10 }$$
So, the correct answer is 'B'.
