Solution

The correct option is D Nucleotides in a nucleic acid
The diester between phosphoric acid and two sugar molecules in the DNA and RNA backbone links two nucelotides together to form oligonucleotide polymers. The phosphodiester bond links a 3' carbon to a 5' carbon in DNA and RNA. So, the correct answer is option D.
