Solution

The correct option is B
Phosphodiester bonds

In DNA, the phosphodiester bond is the linkage between the 3' carbon atom of one sugar molecule and the 5' carbon atom of another, deoxyribose sugar in the DNA. In this manner, each strand of DNA has a backbone of phosphate-sugar-phosphate-sugar-phosphate.
