Solution

The correct option is C DNA Polymerase
For the construction of a recombinant DNA polymerase is not essential. DNA polymerase is an enzyme that synthesizes DNA molecules.

The process of ligation means joining of two fragments of DNA. Therefore we need the fragment of DNA and the gene of interest which is to be joined with the fragment. The enzyme needed to join the fragment with the gene of interest is DNA ligase.
