(C) The double helical structure of $DNA$ is primarily stabilized by hydrogen bonding between the nitrogenous bases.Watson and Crick proposed that specific base pairing occurs between a purine and a pyrimidine ($A=T$ and $G \equiv C$), which is facilitated by hydrogen bonds.These hydrogen bonds provide the necessary stability to maintain the double-stranded helical geometry of the $DNA$ molecule.

The reason for the double helical structure of $DNA$ is the operation of
