Solution
The correct option is C Nitrogenous base and pentose sugar The glycosidic bonds are the bonds that form between the anomeric carbon of sugar (monosaccharide) and the oxygen atom of an alcohol.
In a nucleotide, glycosidic bonds are formed between C'1 of pentose (ribose or deoxyribose) sugar and N9 of purines or N1 of pyrimidines.
