Explanation:

• DNA helicase unwinds the DNA double helix, not build new strands.
• DNA polymerase is the enzyme responsible for synthesizing (building) new DNA strands by adding nucleotides during replication.
• The lagging and leading strands are the newly synthesized strands themselves, not the entity that builds them.
• The replication fork is the site of DNA replication, not the builder of new strands.

Answer:

B. DNA polymerase
