Solution

The correct option is A Phosphodiester bond
A nucleotide consists of a nitrogenous base, a pentose sugar and a phosphate group. A nitrogenous base is linked to the pentose sugar through a N-glycosidic linkage to form a nucleoside. Two nucleotides are joined together by a phosphodiester bond in a molecule of DNA. DNA polymerase helps in forming phosphodiester bond between nucleotides during DNA replication.
