The DNA sequence reads from the bottom to the top of the gel. Based on the ladder marker, we can estimate that the DNA fragment in question is around 300 base pairs long. By aligning the ladder with the bands on the gel, we can determine that the sequence reads AGGCTGACGGA from the bottom to the top. Therefore, the best choice is C.
