Correct Option: C

DNA Polymerase I is a template-dependent DNA polymerase which catalyzes 5′→3′ synthesis of DNA. DNA Polymerase I catalyzes the template-directed polymerization of nucleotides into duplex DNA in a 5′→3′ direction. In addition to polymerase activity, this DNA polymerase exhibits 3′ to 5′ and 5′ to 3′ exonuclease activity. It is able to utilize nicked circular duplex DNA as a template and can unwind the parental DNA strand from its template. Because of its exonuclease activity in the 3′ to 5′ direction, the polymerase can remove or excise the RNA primers synthesized during replication.
