Solution
The correct option is C Phosphodiester bond
During transcription, a nucleotide is incorporated into the RNA chain by making an ester bond between the 3’-OH( hydroxyl group) of RNA chain and 5’ phosphoric acid unit of incoming nucleotide. So between two nucleotides, two phosphoester bonds are present which is also known as a phosphodiester bond.
