Answer:

There are 17 hydrogen bonds in that region.

Step-by-step explanation:

There are 7 pairs of bases. Four of them are between Adenine and thymine, and 3 of them are Cytosine and guanine. Adenine and Thymine form two hydrogen bonds while cytosine and guanine form three. Therefore there are in total 17 hydrogen bonds in that piece of DNA.
