Solution

The correct option is D Double Helix
DNA is a long polymer of deoxyribonucleotides that has a double helical structure with a sugar-phosphate backbone where nitrogenous bases project inside and are paired together with the help of hydrogen bonds, that forms the double stranded structure of the DNA.
So, the correct option is 'Double helix'
