Solution

The correct option is D Nitrogenous bases
The backbone of the polynucleotide is a chain of sugar and phosphate molecules. Each of the sugar groups in this sugar-phosphate backbone is linked to one of the four nitrogenous bases. The four nitrogenous bases are - adenine, thymine guanine and cytosine. These four bases are responsible for the genetic code of organisms.
