Quizplus · Accepted Answer

The complementary base pairs for each of the fragments are:
ACTGT - TGACA
GTGTT - CACAA
GACTC - CTGAG
TTCAAC - AAGTT
ACTGA - TGTCA
TGAC - CTCA
Thus, putting them together in the correct order gives: 
TGACA CACAA CTGAG AAGTT TGTCA CTCA
Which corresponds to the sequence:
AC TGT GTTTC AACTG ATGAC
Which means the correct answer is C.
