Answer:

A. Enzymes break the hydrogen bonds between the nitrogenous bases to separate the two strands of DNA.

Explanation:

DNA replication involves several different enzymes. Enzymes break the hydrogen bonds between the nitrogenous bases to separate the two strands of the DNA molecule. Then an enzyme called DNA polymerase joins individual nucleotides together to form the new complementary strands of DNA. Lastly, the DNA polymerase "proofreads" each new strand to make sure that each DNA molecule is perfect, or a nearly perfect copy of the original molecule.
