Answer:
<em>The correct option is C) The helicase enzyme unwind the DNA molecule into two strands.</em>
Explanation:
DNA replication occurs in a semi-conservative manner. This means that each strand of the DNA can give rise to a new strand. For the process of DNA replication to begin, firstly it is necessary that the DNA unwinds. Topoisomerases are enzymes which are known to remove the super-coiling of the DNA. Helicases can be described as the enzymes which separate the two strands of DNA from the region where replication has to begin. Hence, option C is correct.
