Answer:

Sugars and phosphates  

Explanation:

DNA is deoxyribonucleic acid.

The backbone is based on a repeated pattern of a sugar group (deoxyribose) and a phosphate group.  

The image below shows one straightened-out strand of DNA with a backbone of alternating sugars and phosphates.

A is wrong. There is no ribose in DNA.

B is wrong. The nucleic acids A, C, G, and T join one strand of DNA to the other.

C is wrong. There is no RNA in DNA.
