Sugar and phosphate is the correct answer.

Nucleotide comprises of nitrogenous bases, sugar and phosphate. The nucleotide chain is formed by joining of repeated nucleotide units.
The two nucelotides are joined together by phosphodiester bond. This bond forms between phosphate and two sugar molecules. Therefore, sugar and phosphate are the backbone of nucleotide chain.
Nucleotides can be commonly seen in DNA or deoxyribonucleic acid and RNA or ribonucleic acid.
