Solution

The correct option is A Hydrogen bond
The nucleotides in the two helical strands of the DNA are held together by Hydrogen bonds. The nitrogenous bases are present in an inward direction of the strand. These nitrogenous bases of the two antiparallel strands make hydrogen bonds together and thus, two helical strands are joined.
Thus, the correct answer is (A).
