C is the correct answer. Phosphodiester bonds are formed via condensation reactions between the ribose on one nucleotide monomer and the phosphate on another. They form the sides of the DNA double helix ladder. In DNA, hydrogen bonds between nitrogenous bases form the "rungs" of the DNA double helix ladder. RNA, a single-stranded molecule, lacks these bonds. Peptide bonds between amino acid monomers form proteins. Glycosidic bonds are found in carbohydrates.
