(C) In a $DNA$ molecule,guanine $(G)$ always pairs with cytosine $(C)$ via $3$ hydrogen bonds.Since the fragment contains $5$ guanine bases,there must be $5$ cytosine bases to form complementary base pairs.Total number of hydrogen bonds = (Number of $G-C$ pairs) $	imes$ $3$.Total number of hydrogen bonds = $5 	imes 3 = 15$.
