Solution

The correct option is D $23$
The complementary nitrogenous bases in the DNA are held together by hydrogen bonds. Guanine's complementary pair is Cytosine and they are held together by three hydrogen bonds. Adenine's complementary base is Thymine and they are held together by two hydrogen bonds. therefore, the given sequence has a total of 23 hydrogen bonds as illustrated in the picture. so the, correct option is '23'.
