C) DNA opens up and each strand is used as a template for a new strand.

Explanation:

DNA molecule is present in the form of a double helix. The hydrogen bonds between the two DNA strands are broken down by the enzyme helicase. This enzyme uses the energy of the hydrolysis of ATP to perform the denaturation of DNA. Breaking of hydrogen bonds separates the two DNA strands from each other. Now, each of the DNA strands serves as a template which means that its nucleotide sequence would specify the nucleotide sequence of the newly formed strand. The process is catalyzed by the enzyme DNA polymerase in a primer dependent manner.
