During replication of DNA, which one of the following enzymes polymerizes the Okazazki fragments?

Okazaki fragments are sho segments of DNA synthesized on the lagging strand, during the process of DNA replication. DNA polymerase III is a highly "processive" enzyme that has a 1 g unit which acts as a clamp loader for the lagging strand Okazaki fragments, helping the two b subunits to form a unit and bind to DNA. The polymerization of okazaki strands are done by DNA polymerase III.
