A. enzymes to break the hydrogen bonds of the DNA molecule

Explanation:

For DNA replication to occur it is necessary that the DNA strands separate, as each will be used as a template for the formation of other DNA strands. As we know, the two strands of DNA are joined together by hydrogen bonds, so that the separation takes place, the bonds need to be broken and who does this is the enzyme called Helicase.

The helicase breaks hydrogen bonds between the two strands of DNA, allowing replication to occur.

DNA replications require an enzyme to break the hydrogen bonds that holds two DNA strands together, free nucleotides, and polymerase enzyme to join nucleotides onto the template DNA strand.

During replication, the double-strand DNA is first separated by the helicase enzyme. Thereafter, each strand is then used as a template to synthesize complementary strands.

A primer is attached to the origin of replication and the polymerase enzyme adds free nucleotides to elongate the daughter strand.

Thus, enzymes, free nucleotides, and polymerase are all needed for DNA replication.
