A Correct answer
Explanation

This option is correct. Glycol nucleic acid is a polymer identical to DNA or RNA but differing in the composition of its backbone. DNA and RNA have a deoxyribose and ribose sugar backbone, respectively. GNA's backbone is composed of repeating glycol units linked by phosphodiester bonds.
